Well I go to Ohio State, and root for all of the sports teams except the football team. I find them to be a bunch of recalcitrant douchebags who need a .500 season every three years or so to bring them back down to earth. Just the system present at the university for football players is a joke, and a lie.
I've always had a tremendous amount of respect for Notre Dame. The players go to school (for the most part, my friends on campus say it's so-so), they are immersed in the student body (that is huge for me), and generally seem like actual student-athletes. My cousins were captains of the wrestling and swimming teams and were legitimate students, like the majority of athletes at Ohio State (contrary to popular belief, it really is a great place to go to school). I just have a hard time rooting for the guys on the football team.
I have been and always will be fond of Notre Dame's program, they clearly go about things the correct way. I might ask in return, how could one NOT respect ND?
