The biggest issue in this is (I believe):Almost anything on this list under the $10,000 threshold is probably nothing to worry about other than maybe a few games suspension or virtually meaningless forfeited games. Anything over, start worrying.
If you are aware that a player may have received impermissible benefits, play him anyway, and later find out that they were in fact impermissible, you forfeit all games that player played in. Does MSU (and others) assume that risk or do they sit players immediately?
