From a So cal perspective Michigan fans are many but quite respectful... I like Michigan fans and as our rivals go I respect UM the most, just my two cents... Mind you I have never been to Indiana OR Michigan...but that's the facts out here in LA
I think the night and day of CFB is this:
Best- Nebraska fans, loyal, softspoken, extremely respectful.
Worst- tOSU fans, complex ridden, arrogant, loud mouth and far too often violent (Sox Nation of CFB imo)
SC fans are SO "band wagon Laker fans"... they know NOTHING about the sport, its history or anything else, jump on the wagon during the good times, talk non stop shit like they have a right too, then completely abandon the sport when SC is down... SHOCKS me to think these same BWagon fans for the Lakers and Trojans are the same people wh support the Dodgers in millions no matter what the win loss record is... quite and interesting thing there
SC alums are something else too,... I have been to auctions that UCLA and USC have done for this or that and when the UCLA stuff is being bid on the SC alums will bid just to make the UCLA fans/alums pay huge amounts for their items, AND if they happen to out bid everyone to the point they win the bid they will just leave without the item... that is some smug rich dick shit to do...
LSU fans?? Only know them from TV really and yeah they do seem pretty bad, but have encountered VERY few in person so there you have that
