The Commitment Project: studying recruits, college football edition

That isn't to say an indecisive player can't succeed. After all, safety Tony Jefferson committed to Stanford and UCLA before signing with Oklahoma in 2010. As a sophomore, Jefferson finished third on the team in tackles and will be one of the Sooners' top returning defenders in 2012. Meanwhile, quarterback Tajh Boyd committed to West Virginia and Tennessee before eventually deciding on Clemson. In 2011, Boyd threw for 3,828 yards and 33 touchdowns while leading the Tigers to their first ACC title in 20 years.

"It's been a crazy recruiting trip," Boyd told me when he committed to Clemson on Jan. 27, 2009. "I'm glad to have it behind me." Boyd's recruitment illustrates the difference between player-driven decommitments and school-driven decommitments. Boyd's first flip, from West Virginia to Tennessee, was his choice. He considered Tennessee a better destination than West Virginia. Had it been up to Boyd, he probably would be a Volunteer now. Boyd said that days before he committed on Nov. 1, 2008, then-Tennessee athletic director Mike Hamilton told him Phillip Fulmer would remain Tennessee's coach. "He ended up firing Phillip Fulmer like two or three days after I committed," Boyd said in 2009. New Tennessee coach Lane Kiffin didn't believe Boyd could run the pro-style offense Kiffin planned to use. So Kiffin cut Boyd loose. That was a school-driven decommitment.

Unlike in Winn's basketball project, which attributed 37.4 percent of decommitments to school factors (coaches leaving, NCAA sanctions, etc.), the football players tended to decommit for more personal reasons. Of the 73 decommits, 59 (80.8 percent) changed their minds because of player factors.

Coaching changes played a much smaller role than expected, though two changes in particular had an outsize impact on top-100 players. Nebraska's firing of athletic director Steve Pederson and coach Bill Callahan in 2007 affected the choices of quarterback and future NFL first-rounder Blaine Gabbert (Missouri), offensive lineman Trevor Robinson (Notre Dame), tailback Jonas Gray (Notre Dame) and offensive lineman Bryce Givens (Colorado).

Meanwhile, Kiffin's brief tenure on Rocky Top caused quite a bit of chaos in this sample. In addition to causing Boyd's flip, Kiffin flipped receiver Nu'Keese Richardson from Florida, safety Janzen Jackson from LSU, tailback Bryce Brown from Miami and defensive end Corey Miller* from Florida State. Later, Kiffin's abrupt departure to USC would cause defensive end Brandon Willis to flip from Tennessee to North Carolina. (Willis would later transfer to UCLA, then back to North Carolina, then back to UCLA. He has yet to play a down, but he is expected to play for the Bruins in 2012.) At USC, Kiffin would sign former Tennessee commit Markeith Ambles, a receiver who has since left the program. Of all the players listed above, only Miller -- who never actually played for Kiffin -- is still with Tennessee's program.

* Miller joined the Vols in 2010 and played for Derek Dooley, but Kiffin and his staff initially sold Miller on Tennessee, so Kiffin gets credit/blame for the flip.

It's fitting that Kiffin and Florida-turned-Ohio State coach Urban Meyer, who locked horns so memorably on the recruiting trail, finished tied for the title of Top Flipper. Each flipped five top-100 players during the five-year period. Kiffin's flips are outlined above, while Meyer swiped tight end Aaron Hernandez from Connecticut, offensive lineman James Wilson from USC, linebacker Jerimy Finch from Indiana, quarterback John Brantley from Texas and defensive tackle Omar Hunter from Notre Dame. In his first recruiting cycle at Ohio State, Meyer has proven that his commitment-cracking skills didn't erode at all in his year away from coaching. In less than two months, Meyer has flipped offensive tackle Taylor Decker from Notre Dame, defensive lineman Se'Von Pittman from Michigan State and defensive lineman Tommy Schutt from Penn State for the class of 2012.

Thanks to swipes by Meyer and Kiffin's successors, Florida and Tennessee tied for the most top-100 players flipped with six each. Florida and USC, meanwhile, tied for the most top-100 players lost with six each.

Florida can probably add another loss to the list for the class of 2012. Mike Davis, a tailback from Stone Mountain, Ga., ranked No. 63 in the 2012 Rivals100, decommitted from the Gators in December. He has since committed to South Carolina. Meanwhile, all eyes have turned to Berkeley, Calif., since mega-recruiter Tosh Lupoi left Cal to become the defensive line coach at Washington. That move touched off rampant speculation that Cal wouldn't be able to keep its star-studded class together. Perhaps most telling was a tweet from Sacramento safety Shaq Thompson. Thompson, the No. 4 player in the Rivals100, already has committed to, decommitted from and recommitted to Cal. Could he be pondering another change of heart?

"It's a business," Thompson tweeted. " ... have to do what's best for me."
