Michigan Wolverines: Andrew Rodriguez

National signing day is less than 48 hours away, and Big Ten fan bases are preparing to officially welcome the 2014 class. My interest in recruiting has increased during the years, but I likely will never reach the mania of many fans.

The reason: There have been so many examples of supposed top recruits who go bust, and under-the-radar guys who become stars, especially in a largely developmental league like the Big Ten. Recruiting evaluation is an inexact science.

As we prepare for the faxes to roll in, especially from the Big Ten prospects in the ESPN 300, it's always interesting to take a look back at how the top Big Ten recruits from four years ago performed. There wasn't an ESPN 300 back in 2010, just an ESPN 150, which included 15 Big Ten players. Some became stars, some never got started and others haven't closed the book on their college careers.

Let's take a closer look (positions listed according to ESPN recruiting profiles):

Top 50

  • No. 12: Demar Dorsey, S, Michigan -- Although Dorsey signed with Michigan, he was denied admission to the school. He had a checkered past but reportedly was given no specific reason for the denial. Dorsey appeared headed to Louisville but never made it and played for Grand Rapids Community College in 2011. He planned to transfer to Hawaii in 2012 but never played for the Warriors.
  • No. 42: William Gholston, DE, Michigan State -- Gholston played three seasons for the Spartans, recording 142 tackles, including 30 for loss and 10 sacks. He started 24 games and stood out in bowl wins against Georgia and TCU. After a big performance in the 2012 Outback Bowl, Gholston appeared on several preseason watch lists but underachieved at times during the 2012 campaign. He skipped his final season and was a fourth-round pick in the 2013 NFL draft.
Nos. 51-100

  • No. 56: Rod Smith, RB, Ohio State -- Smith redshirted the 2010 season and has been in a reserve role the past three seasons, playing briefly at linebacker in 2012. He has 83 career rushes for 448 yards and four touchdowns. Smith once again will compete for the starting job this fall.
  • No. 66: Khairi Fortt, LB, Penn State -- He played two years for Penn State, recording 50 tackles, including 6.5 tackles for loss and 2.5 sacks, before transferring to Cal in 2012 when the NCAA imposed sanctions on PSU. Fortt sat out the 2012 season because of injury and had 64 tackles (3.5 for loss) in nine games last season before suffering an arm injury. He declared for the NFL draft last month.
  • No. 70: Dakota Royer, DE, Penn State -- Royer didn't play at linebacker in his first two seasons, moved to tight end after spring ball in 2012 and moved back to linebacker early in camp. He then decided to walk away from football, remained on scholarship and graduated in May.
  • No. 80: James Louis, WR, Ohio State -- Louis redshirted the 2010 season and then opted to transfer from Ohio State to Florida International. He never played for FIU and is no longer listed on the roster.
  • No. 82: C.J. Fiedorowicz, TE, Iowa -- He appeared in every game during the past four years and started the past two-and-a-half seasons, earning first-team All-Big Ten honors from the coaches as a senior in 2013. Fiedorowicz had 91 career receptions for 899 yards and 10 touchdowns, including six this past season.
  • No. 88: Evan Hailes, DT, Penn State -- Hailes redshirted in 2010 and played two games in 2011, recording two tackles. A series of blood clots, which first surfaced in the spring of 2011, ended his career in 2012. He remained with the team in a coaching role.

Nos. 101-150

  • No. 112: Rob Bolden, QB, Penn State -- Bolden in 2010 became the first freshman quarterback in 100 years to start a season opener at Penn State. He made 16 starts in two years at Penn State but transferred to LSU after the NCAA imposed sanctions on the program in 2012. Bolden has yet to play for the Tigers and has one season left.
  • No. 118: Miles Dieffenbach, C, Penn State -- Dieffenbach redshirted in 2010 and didn't play in 2011 before starting 23 games the past two seasons at left guard. He'll likely enter the 2014 campaign in the same spot.
  • No. 128: Devin Gardner, QB, Michigan -- Gardner appeared in 12 games as a reserve quarterback in his first two seasons before alternating between wide receiver and quarterback in 2012, starting the final four games under center. He started 12 games at quarterback in 2013 and passed for 2,960 yards and 21 touchdowns, delivering several huge performances and also some duds. Gardner, who received a medical redshirt for the 2010 season, returns for his final year this fall.
  • No. 131: Darryl Baldwin, DE, Ohio State -- Baldwin worked as a reserve defensive lineman in 2011 before moving to offense in the spring of 2012. He played mostly special teams in 2012 and backed up left tackle Jack Mewhort the past two years. Baldwin could move into a starting role in his final season.
  • No. 137: Corey Brown, WR, Ohio State -- After recording just 22 receptions in his first two seasons, Brown emerged as the Buckeyes' top option in the passing game as a junior and senior. He combined to record 123 catches for 1,440 yards and 13 touchdowns and earned second-team All-Big Ten honors in 2013 from the coaches.
  • No. 147: Andrew Rodriguez, G, Nebraska -- Rodriguez played mostly in a reserve role for his first three seasons and then started every game as a senior in 2013, alternating between right tackle and right guard for an injury-plagued Husker line. He earned honorable mention All-Big Ten honors from both the coaches and the media.
  • No. 148: C.J. Olaniyan, DE, Penn State -- After redshirting in 2010, Olaniyan recorded 18 tackles and a sack during his first two seasons. He started every game last fall at defensive end and led Penn State in both sacks (5) and forced fumbles (3), recording 11 tackles for loss, an interception and a fumble recovery. He'll enter his final season projected as a starter.

More misses than hits in the group, although several players still could finish their college careers as stars.
It's time to jump back into our preseason position rankings with a look at the offensive line units.

On Friday, we ranked the top individual players at the position. These unit rankings reflect star power as well as depth. We're heavily weighing these on last year's performance, along with potential for the 2012 season.

Away we go:

1. Wisconsin: Sure, the Badgers lost two All-Americans (Kevin Zeitler and Peter Konz) from last year's line. But they've earned the benefit of the doubt for their ability to reload up front. Left tackle Ricky Wagner is an Outland Trophy candidate, and center Travis Frederick should be one of the best in the Big Ten. The key will be how the new-look right side with Rob Havenstein and likely Robert Burge moving into starting roles.

2. Michigan: The Wolverines might have the top tackle in the league with junior Taylor Lewan, and guard Patrick Omameh is a three-year starter. Senior Ricky Barnum is taking over for David Molk at center. Michael Schofield should be solid at right tackle, though the left guard spot remains a competition. It should be a strong starting group, though depth here is a major concern.

3. Michigan State: This could be the best offensive line Mark Dantonio has had in East Lansing. Six players who started games last year are back, and there will be depth and competition at several spots. Third-year starter Chris McDonald is one of the league's top guards, while tackles Dan France and Fou Fonoti are dependable.
