Yes, he is. A good friend of mine is a significant UConn booster and knows Geno well. I have played in a couple of member-guests with him and Geno (he is a pretty good golfer - about a 3-4 handicap). I was impressed with how much he stayed in touch with former players and how much he knew about their lives. Yes, as you would expect very competitive but a really good guy.
No one can burn a bridge like the UConn Huskies. You have to give them credit, they're like Costanza wearing Babe Ruth's uniform. They don't hold back.
Maybe having ESPN located in their state makes them feel entitled to let loose? Who knows. But I always enjoy the read.
