Spring answers:

1. End game: The Buckeyes have to replace all four starters up front, and while the defensive line isn't quite as deep and is far from a finished product, the future looks pretty bright on the edge. Sophomores Noah Spence and Adolphus Washington were among the top prizes in Urban Meyer's first recruiting class with the Buckeyes, and that talent is already starting to shine through as they slide into first-team roles heading into the fall. Spence is a dynamic force with his ability to use speed to get to the quarterback, and Washington isn't exactly sluggish despite all the strength in his 293-pound frame. The two combined for seven sacks in the spring game, and the Buckeyes are expecting similar performances when it actually counts.

2. Air it out: Miller has proven what he can do with his legs, and Ohio State didn't really need to see him show them off in the spring. The emphasis was on continuing to develop the junior quarterback as a passer, which meant a heavy dose of play calls forcing him to put the ball in the air and a quick whistle if he tried to scramble. The results for Meyer were encouraging. His efficient, 16-for-25, 217-yard performance in the spring game showed a much more accurate delivery and better decision-making that hints at bigger things from the fifth-place finisher in last year's Heisman Trophy race.

3. Backfield stable: One thing that might keep Hyde from giving Meyer a 1,000-yard running back this season is all the teammates fighting to snag a few of his carries. The rising senior is the clear cut No. 1 to partner with Miller in the backfield, and Hyde didn't have to earn that job in the spring after piling up touchdowns last fall and finally tapping into his enormous potential as a rusher. But while he was watching some reps, Rod Smith, Bri'onte Dunn and Warren Ball all showed their upside this spring, which has the Buckeyes even toying with a diamond formation that gets three tailbacks on the field at the same time.

Fall questions

1. Filling out the front seven: Shazier is certainly a fine place for any defense to start, but the Buckeyes would obviously prefer if there were at least one other returning starter joining him in the front seven. There are high hopes again for junior Curtis Grant at middle linebacker, but he's been tabbed as a first-team guy before coming out of spring only to fizzle in the fall. Ohio State will need Grant and sophomore Joshua Perry to help lead the charge as it tries to add depth and talent at linebacker to stabilize a defense that will feature a lot of new faces.

2. Fresh blood: There wasn't a great option to fill Meyer's vaunted H-back position last fall, so the Buckeyes effectively had to put the hybrid spot, made famous by Percy Harvin at Florida, on the shelf. Jordan Hall's return from injury makes him a candidate to diversify the offense, but a handful of recruits the Buckeyes landed in Meyer's second class would could really take the spread to another level. Speed-burners such as Dontre Wilson or Jalin Marshall will be watched closely in August as they could become factors for the Buckeyes as early as September.

3. Something special: If the Buckeyes score as easily and often as it appears they might, maybe it won't matter who handles the kicking game. But Meyer has always taken pride in his special teams, and at this point there is still some uncertainty as Drew Basil is pressed into action as both a kicker and a punter. In the big picture, the changes on defense are far more critical -- but close games usually pop up along the way for teams trying to win a championship, and Basil might need to pass some tests for the Buckeyes.

COLUMBUS, Ohio -- Last year, Ohio State led the Big Ten in scoring at 37.2 points per game. Great, right?

Not in the minds of the Buckeyes, who thought they could have fielded a much better all-around attack.

"I feel like last year we didn't play a complete game as an offense," running back Carlos Hyde said. "Some games it was all running, while others it was just passing."

Head coach Urban Meyer rarely seemed happy with the offensive production last year, outside of the running skills of Hyde and quarterback Braxton Miller. He often expressed his dissatisfaction over a lack of speedy playmakers and an inconsistent passing game.

"I'd get frustrated," Meyer told ESPN.com. "But the bottom line is, name an offense that doesn't have guys who make people miss and are dynamic with the ball in their hands, and that's not a great offense. We don't have enough."

The names on offense haven't really changed much this spring. But the hope is that with another year of understanding the system, some improved throwing and catching and maybe some reinforcements from the recruiting class, the Buckeyes will come closer to fulfilling Meyer's vision of a truly great offense.

It all starts, of course, with Miller, whose efforts to become a more accurate passer this offseason have been well documented. Ohio State also needs continued development from its receivers, which is not a very deep group right now. Meyer singled out Corey "Philly" Brown, who led the team with 60 catches for 669 yards, as someone who's becoming one of those dynamic playmakers he's seeking.

"I've tried to work on my open-field running and body control so I could cut faster," Brown said. "It's really paying off for me right now."

Brown is the clear No. 1 receiver, but he needs more help. The team has only six scholarship receivers this spring, and offensive coordinator Tom Herman said he'd only feel comfortable playing four of them for a whole game. Devin Smith made some highlight-reel catches on deep balls early last year but was less effective down the stretch, as he had only 13 receptions in the final eight games.

"People, for lack of a better term, figured him out," Herman said. "He wasn't a very versatile guy. He did a couple of things really well, but the other things that he tried to do, he was very below average. He's starting to improve some of his weaknesses to be a more complete receiver, and he has a lot of physical tools and a great attitude."

Herman said Chris Fields has had a really good spring, and Evan Spencer is a reliable target. Sophomore Michael Thomas, the star of last year's spring game, has shown flashes of his talent but needs to progress in a lot of areas. Herman called the receiver depth "a bit scary right now." But the Buckeyes recruited several receivers in this year's class, including Jalin Marshall, Dontre Wilson, James Clark and Corey Smith. They're hoping at least one or two contributes right away.

"You hate to count on [recruits] because they're usually overrated," Meyer said. "But that's why we went out and recruited them."

"We're not asking them to come in and be Jerry Rice," Herman said. "We just hope they can provide some depth and maybe add some skills that we don't currently have in that room right now."

One area certainly not lacking in depth is at running back, where Hyde returns after rushing for 970 yards and 16 touchdowns last year. Rod Smith is having a good spring, Warren Ball appears to be coming on and if sixth-year senior Jordan Hall can ever stay healthy, he'll provide lots of versatility. There was a buzz last week in practice when the Buckeyes lined up with Hyde, Smith and Ball in the same backfield with Miller in a formation Meyer cribbed from the San Francisco 49ers.

"That can give a bunch of trouble to defenses," Hyde said. "They just see three big backs in the backfield and a quarterback who can also run the ball. They don't know who's getting the ball or who's going where."

Ohio State's offensive players do know where they're going, which is different than last spring. Now in the second year of the system, Herman says he can teach his guys not just what to do but why they're doing it.

"It's not just the memorization of, 'OK, I have to line up on the left here,'" he said. "I could train a monkey to do that. What separates really good offenses from average to below-average offenses is all 11 guys understanding the big picture, the entire concept and scheme we're trying to accomplish. It's been nice to kind of dive into that with all of our players this spring."

Knowing how to change a route against a certain defensive look, for instance, should help the Buckeyes play faster this year. The coaches have challenged the players to be a Top 5 offense in the nation this year. That's a lofty goal, but remember that this team is starting from an already high level despite its flaws.

"I definitely think we can be one of the top offenses in the country if everybody takes care of business and is mistake free," Brown said.

With national signing day in the books, the next big date on the Ohio State calendar as it continues working toward an encore for an undefeated season in 2013 is spring practice. Before those workouts begin, BuckeyeNation will take a look at each position to see where the roster is at -- and where it's going.

KICKOFF RETURN/PUNT RETURN

• Who's back: The jokes about Philly Brown not being able to make anybody miss at wide receiver had already started subsiding, but he put them to bed for good on special teams. The rising senior put two exclamation points on a breakout individual season with a pair of punt returns for touchdowns, including a pivotal one in the overtime thriller on the road against Wisconsin that helped save the undefeated campaign. The kickoff return gig wasn't quite as stable and the unit overall was never able to really provide the type of spark coach Urban Meyer wants in that phase of the game. But before a freshman class loaded with speed arrives in the fall, he's got a handful of guys with experience to look at this spring -- starting with running backs Rod Smith and Bri'onte Dunn, wide receiver Devin Smith and perhaps cornerback Bradley Roby.
• New faces: The Buckeyes have two new additions already on campus at a skill position, though Eli Apple and Cam Burrows will likely be focusing more on learning the schemes and techniques at cornerback than trying to provide competition at the return slots. But when training camp rolls around, though, Meyer might be looking closely at burners such as Dontre Wilson, Jalin Marshall, James Clark, Corey Smith or touted tailback Ezekiel Elliott to help carry the load.
• Projected spring depth chart: Brown should head into camp with the edge on the punt-return unit, with fellow wideout Devin Smith in the second slot. Kickoff return could easily be staging a wide-open competition, though Rod Smith and Dunn ended last season as the top two options and figure to start camp there as well.
• Numbers game: The Buckeyes finished the season ranked just No. 84 in the country in average kickoff return yardage, managing less than 20 yards per attempt and never posting one longer than Rod Smith's 36-yarder. The junior running back was also the most consistent threat among the handful of returners the Buckeyes tried, leading the team with an average of 23.3 yards on his 13 attempts.
• One to watch: The influx of speed at the skill positions in the fall should give Meyer even more options to play with, but he could be faced with the same decision then that he does now. Is it worth exposing Roby to a few more hits to take advantage of his speed? The junior cornerback has a gear that few other athletes can match and it's not hard to imagine him putting that speed to good use with the ball in his hands on special teams. But he's also integral on defense with his lockdown coverage and disruptive ability in the secondary, which will give the Buckeyes something to ponder as they try to find some explosiveness in the return game.
• He said it: "We maybe didn't have the home-run hitter, explosive, open-space player on offense, but you know what? Some guys really grew up and did a good job for us. Philly Brown did a nice job." -- Meyer on signing day
