At least in the pros, you have a semblance of parity and the chance a team can get hot at the right time (see Giants last year in the playoffs).
College football: Same dominate teams year in and year out. Spend early season beating up weak opponents looking for a payday. One loss and out. '
Also, coaches in the college rank seem to be higher on the dick/smarmy level (Spurrier, Saban, Nutt, et al).
Plus, the college game is hypocritical. Just pay the players over the table.
Also, I think the college game, minus a few teams, is more boring than the pros unless you go/went to a school and root for it no matter what.
And finally, the BCS is screwed and the bowl games are a joke except for like 1 year.
