The UNC-dook rivalry is definitely going to change. For better or worse, Coach K was a nemesis. He was hated. That makes the rivalry stronger. Rivalries need hatred, on some level.
Jon Scheyer, Tony Bennett, and Hubert Davis are fairly, if not very, likable people.
If Jerry Stackhouse became the coach, then a lot of new rivalries might occur! He's got that ****-you'ness about him. Coach K had that. Dean and Roy had it on a more subtle level. I'm not saying I want Jerry Stackhouse to be the coach. I'm simply saying that the coach's personalities contribute to teams and rivalries.
I think Pitt and UNC might be a future rivalry. The Capels are jag-offs. Rivalries need jag-offs!
