Holker had an issue with Arod and playing time. Then proceeded to act in the most unprofessional way he could possibly have acted.
Keenan Pili: Never fully recovered from his ACL injury and wasn't getting playing time this past year. Didn't contribute much at TENN. Not a loss. Pili was politely told he wasn't going to play much.
Gabe Jeudy-Lally: Left for other reasons and either you are naive to those or you are being disingenuous.
Dallin Holker: May be a legit point, but he handled himself terribly
Clark Barrington: Everyone assumed he was going to the NFL, went to play with his brother.
Campbell Barrington: Was getting beat out and didn't want competition, clearly showed last year he wasn't ready
Tate Romney: Wouldn't have started at BYU nor cracked 2 deep. Who would he have replaced?
Logan Fano: Not even going to address this one.
Holker is the only real loss on this list.
