Potential. All due respect, I haven't seen Brett on the two deep and I don't believe he has seen meaningful time thus far. Additionally, Brett's transgression as far as I know has been limited to underage drinking. I think many of us would have an issue if this incident (again 1 incident) led to his removal from the team.
I have zero inside knowledge, but I have a hard time thinking NU would suspend a player twice for violating rules during a season and then have him continue to get arrested in the offseason and still let him remain a part of the team . If the violation is deemed serious, I suspect we would boot ant player immediately off the squad, including someone the caliber of Ant.
As far as Oklahoma, this is the same school that has Joe Mixon on its roster after he broke 4 bones in a woman's face in a domestic. Yes, he got suspended a year, but only after pressure. Mixon was considered a top RB recruit. Thomas has Legitimate pro potential and might be the OK's top returning defense player. Yesterday, I think you have a prime example of an institution that enables behavior, especially if you are stud player.
