I'm guessing grade issues would be the first item to consider as being "on record". A player who has a bunch of progress reports showing failing scores suddenly ends every semester on the Academic Honor Roll.
Next I'd wonder if there were records that could prove the coaches were working with players during NCAA unapproved times. If there were notes about practice performance when the team wasn't supposed to be practicing, there could be sanction issues to consider.
I'm sure there are many more and surely more severe possibilities. Those are just the first two that popped into my head.
