For Matthews? He was integral to student body right, John McCay called him one of the best lineman he'd ever seen, consensus two-time all American, and was drafted #9 overall, presumably based on his college output. That's a pretty solid for a guard.
But if you want someone else, won't hurt my feelings. I hate USC. Even more than Minnesota, Iowa, Ohio State, Michigan, and Alabama.
Barry Sanders is the biggest snub here, and John Elway is the next most deserving, IMO.
