Alabama Crimson Tide

The SEC and Big 12 announced an annual challenge on the basketball court, but colleague Edward Aschoff wondered what it would look like if that challenge extended to the football field.

There are already two games on the schedule this season -- between TCU and LSU, and Oklahoma State and Mississippi State. What else would I like to see?

Let me start by saying that renewing the Texas-Texas A&M and Missouri-Kansas rivalries are a given. I'm omitting those matchups, but I'd love to see them.

Let's get started:

Oklahoma State vs. Alabama: OSU narrowly missed out on playing for the national title back in 2011, and both are among their conference favorites again in 2013. When the BCS "snubbed" the Pokes after the 2011 regular season, OSU coach Mike Gundy half-jokingly suggested these two play for the right to play LSU in the title game. It would be fun to see this one finally played out on the field.

Baylor vs. LSU: Straight up offense vs. defense. That's the Big 12 vs. SEC debate at its heart. Baylor just might be the Big 12's best offense, and LSU will put together another strong defense. These are the matchups we want to see. The Big 12 has faltered on the big stage, helping the SEC stretch its run of national titles, but seeing Bryce Petty sling it around against an athletic defense would be a lot of fun.

Texas vs. Arkansas: Arkansas' exit from the Southwest Conference helped usher in the birth of the Big 12 after the SWC crumbled. Texas has bigger rivals like Oklahoma and Texas A&M, but these two played some of the greatest games in college football history, and as an Arkansas native, I've seen up close how much Razorbacks fans detest the Longhorns to this day. The result would be a great game and a hyped atmosphere.

TCU vs. Texas A&M: Texas A&M fans take exception to the idea that TCU was an on-field "upgrade" over the Aggies in the Big 12. The Aggies largely struggled in the Big 12 after some early success and a Big 12 title under R.C. Slocum. Since leaving for the SEC, the Aggies have gone nowhere but up, and ended 2012 as the hottest team in college football. Aggies quarterback Johnny Manziel has a Heisman Trophy. Could he shred the Frogs? Want to prove TCU is not an upgrade? Beat TCU on the field.

Kansas State vs. Florida: Kansas State is perpetually underrated and wins with a bunch of junior college guys, and high school players overlooked by major programs. Florida won big under Urban Meyer, but has been largely overrated since Meyer left and was whacked by Louisville to end 2012. The Gators would be suiting up an army of recruiting stars, but could Bill Snyder, the Manhattan Magician, grab a win for the Big 12?

ESPN draft guru Mel Kiper Jr. is rolling out his early top five rankings at each position this week.

Here's what he's looked at so far:

• Wide receivers and defensive ends
• Running backs and safeties

Now, we're taking a look at Kiper's top quarterback and cornerback draft prospects. We'll start with the quarterbacks and look at the corners later today.

Texas A&M's Johnny Manziel ranks third on Kiper's list, while Alabama's AJ McCarron comes in at No. 5. Ole Miss' Bo Wallace made Kiper's "Next up" list, while Georgia's Aaron Murray made his "More I like" list.

Manziel is getting all sorts of draft attention after his record-breaking, Heisman-winning season. He's the most talked about quarterback in the country and while he doesn't have an elite arm, he's extremely athletic and slippery. He's looking to develop more into a passer, but his ability to improv will continue to help him when his arm can't.

McCarron is someone who could have left for the NFL this year, but decided to stay in school. He makes great decisions with the ball (he threw 30 touchdowns to three interceptions last season) and certainly knows how to win. He has two national championship rings and is going for his third straight. He hasn't been asked to do a lot at Alabama, but he's put up some pretty good numbers and is easily the most talented quarterback Saban has had at Alabama.

Wallace has a tremendous amount of athleticism, but he had a lot of decision-making issues last year. He threw for nearly 3,000 yards, but threw 22 touchdowns to 17 interceptions. Fixing his turnover issue is the biggest thing Wallace has to work on this fall. He has good arm strength and can get out of trouble situations with his feet.

Then you have Murray, who isn't getting a lot of draft love. He flirted with heading to the NFL, but also decided to stay in school. Murray's height (listed at 6-1) has hurt his draft status, but he has a solid arm, moves around well with his feet and has really improved his decision making. He had the stigma of not coming up in big games, but showed improvements in 2012 with his second-half effort in the Dawgs' win against Florida and with the way he played against Alabama in the SEC championship game. He'll probably end the 2013 season with a handful of SEC/Georgia records and should become the first SEC quarterback to throw for 3,000 yards in four straight seasons.

Other draft-eligible quarterbacks I'm keeping an eye on this fall:

• Jeff Driskel, Florida: He wasn't great last year, but there's no denying Driskel has talent. He's more comfortable with the playbook, and he has a lot more confidence. He must have more command and develop better chemistry with his receivers this fall.
• James Franklin, Missouri: He spent most of last season battling injuries, but finally isn't dealing with excruciating shoulder pain. His confidence was up this spring and that will go a long way this fall.
• Zach Mettenberger, LSU: He really came along in November and has all of his receiving targets back. People at LSU feel like he's much more comfortable with Cam Cameron's guidance.
• Tyler Russell, Mississippi State: He's had an up-and-down career with the Bulldogs, but when he was on last year he was extremely efficient. He lost all of his receivers from last year and can't press like he did late last season.
• Connor Shaw, South Carolina: It's hard to find a tougher quarterback out there. Shaw has dealt with a lot of injuries, but when he's been on the field, he's had a lot of success. Here's a chance for him to really improve his draft stock.

During the summer, TideNation will analyze each of the scholarship players on the Alabama roster -- excluding the Tide's 2013 recruiting class -- in our Crimson Countdown series. Starting with No. 1 Dee Hart, we will go through the roster numerically, finishing with No. 99 Brandon Ivory.

No. 4 T.J. Yeldon
Sophomore running back

Expectations for 2013: Where does Yeldon go from last season? A spot on the All-American team? A seat in New York for the Heisman Trophy ceremony? Honestly, after a freshman campaign in which he outperformed Eddie Lacy at times, it's hard to imagine what Yeldon will do next. One thing is certain, though. He'll be the unquestioned starter at running back this season and will carry the ball upwards of 15 times per game.

Best-case scenario: If he hasn't already peaked, it's hard to believe he isn't close to maximizing his full potential. But for Yeldon to truly cement himself in the conversation of great Alabama tailbacks, he must stay healthy. And with Alabama's penchant of sharing the football, he should avoid the wear and tear usually put upon featured backs. At the end of this season, don't be surprised if it's Yeldon in the Heisman conversation, not quarterback AJ McCarron. Only one running back has won the award since 2000, but that man was Mark Ingram.

Worst-case scenario: If it were even five years ago, Yeldon would be in line to get the ball 25 times a game this season. As it stands now, that won't happen. Alabama likes to rotate in at least three backs and save its featured back some tread on the tires, and that will be the major argument against Yeldon in a Heisman conversation. He simply won't have the reps of what Ron Dayne or Ricky Williams -- two of the last three tailbacks to win the award -- had in college.

Future impact: Barring injury, Alabama fans are looking at two more seasons of Yeldon carrying the football. Because of the short shelf life associated with running backs, don't expect him to stay any longer than that. As Saban said of Lacy's decision to turn pro early: "When you’re a running back in the NFL, it’s the shortest shelf-life of any position. So I kind of get it; I get where you’re at.’"

No. 3 Vinnie Sunseri
Junior safety

Expectations for 2013: It's not a make-or-break year for Sunseri, but it's awfully close. A standout as a freshman in 2011, he took a step back as a sophomore, faltering in coverage a few too many times in key games. It was a clear indication again of where the junior's talents lie: in space, not one-on-one against a speedier receiver. Expect Sunseri to compete for a starting job but get rotated out depending on the situation. If it's a running team and he's needed near the line of scrimmage, he'll play significant reps. If it's a passing team that goes four- and five-wide, then he could be used sparingly.

Best-case scenario: He's got the experience and he has the trust of the coaching staff. For that alone, he'll have a leg up on Landon Collins for the starting safety spot opposite Ha'Sean Clinton-Dix. Sunseri has seen action in 27 of 27 games in his career, and he's shown in that time that he's capable of being a playmaker on the field. We've seen his nose for the football on special teams and we've seen it from a utility role on defense. The question is whether he can become a contributor on every down.

Worst-case scenario: The talent disparity between Collins and Sunseri is obvious. And while player rankings can be overrated, the difference between the No. 1 safety in his class and the No. 18 outside linebacker is fairly significant. Collins, of course, is the former in that scenario and Sunseri the latter, and this spring we got to see why as the former five-star prospect from Louisiana made big play after big play at A-Day. He'll push Sunseri and fellow safety Nick Perry for the starting job throughout the fall.

Future impact: Whether it's as a starter or a reserve, Sunseri will have an impact on the Tide for the next two seasons. What he does on special teams and from a leadership standpoint cannot be overvalued. There might be more talented guys on the roster, but the experience Sunseri brings to the table will be enough to keep him on the field in some form or fashion.
