There is an unknown about how the NFL will treat any potential Harbaugh college suspension. In the past, they have elected not to be safe harbor for people fleeing NCAA suspension. Notably Jim Tressel and Terrell Pryor had to serve an NFL suspension prior to entering the league for things that happened in college.
Buddha is correct about Warde. He’s not shown any competence in his AD role. He shouldn’t be trusted to make any meaningful decisions. The football program has flourished without his involvement and he has probably hindered it more than helped. I doubt Harbaugh is still there today if Santa Ono hadn’t been there to take the reins during negotiations. The guy has proven to be quite a turd as AD.
