Decommitment rankings: 2015

There are certain facts you have to accept if you love college football. Ohio State and Michigan fans just aren't going to get along. The Lone Star State still isn't big enough for both Texas and Texas A&M. And football recruits are going to change their minds -- a lot. Here's a look at the 10 biggest decommitments for the class of 2015, including a new entry from Blake Barnett, who has backed away from a longtime Notre Dame commitment.

Michigan1. George Campbell
ESPN 300 rank: 11
Position: ATH
Height/Weight: 6-foot-4/187 pounds
Stars: 5
Originally committed to: Michigan
Looking at: Alabama, Clemson, Florida, Florida State, Michigan, UCLA
The impact: When Campbell committed to Michigan, it looked like the Wolverines had pulled off a major recruiting coup. Getting one of the best players in the nation is always a big deal, but getting one of the best players out of Florida and away from national champion Florida State and the SEC powers is an even bigger deal. It would have surely given Michigan the momentum to sign one of the nation's best classes, but without him, the Wolverines aren't in the top 15 and still are looking for their impact pass-catcher.
