College football is not just about practice, the games and recruiting, although those are the aspects on which the most emphasis and hype is placed.
There is another aspect, technically, part of recruiting, that can have a major impact on a team—transfers.
Take the case of Russell Wilson. Wilson transferred from N.C.State to Wisconsin back in 2011, and wound up taking that Wisconsin team from good to a Rose Bowl and a Big Ten title.
While there are not any such high profile transfers becoming eligible to play this season, there are several teams that are going to be impacted by the transfers.
Jake Heaps, the BYU quarterback who is now at Kansas and will be at the front of the pack for the starting job, is one of the top transfer prospects at the position, and you better believe the Jayhawks will be a different offense with a decent quarterback at the helm.
Like the Jayhawks, each team on this list will be significantly impacted due to transferred players who are currently eligible to play.
