From the suspensions, it sounds like whatever it was was less then some of the things that have gone on over the last couple of years. Fahu Tahi was suspended for a game two years ago for a minor offense. I have to assume it is less than whatever he did because these players were only suspended from practice and could be back for the game if they complete their tasks.
I have never attended BYU, and only know the big things from the Honor Code (drinking, sex, drugs, etc.). I have to assume, based on the type of suspension that it was one of the lesser offenses that was violated.
Kessman from what I can tell has been a major disappointment. He got no mention during fall practices on this board, was never really considered on the two-deep from what I can tell.
Please let me know if I am mistaken on any of these issues.
