When fall practice hits, coaches all know what they have to work with. The practice sessions to determine who plays at what position are already over (though starting roles may still have to be ironed out). Every team has a lot of work to do simply to maintain success.
However, there are dozens of teams who have the deck stacked against them this coming season.
Here are the 25 teams with the most work to do this fall. From the American Athletic Conference to the Pac-12, every BCS-AQ conference is represented by at least one team.
The teams are presented in alphabetical order.
*Auburn is not listed, because Gus Malzahn should be able to rearrange the current talent to a satisfactory result with little work beyond what has already been done through the spring workout period.
