My dad taught me to try to avoid using the word "hate" as it's a bit too strong. He said use, dislike instead. That being said....
I watch Duke a lot because I like college basketball and live in the east....and that's what's on the tube - a lot (Big East too). I choose to watch.
I compare Duke to the Dallas Cowboys and New York Yankees - you either like em or not! Most folks have a side. You're either for em or against em.
Look, I live in our Nations Capital. Few go to see the Wizards or Nats anymore (Caps are a different story - everyone follows a winner ya know). My point being when the Yanks or the Cowgirls come to town (any town) - many either go to cheer for their team or cheer against the other disliked team. As was stated before (Nebraska and ND) if the Devil Rays or Angels come to town you either cheer for your team....or don't go.
Does this come from years of success, overexposure, personailty issues, etc.? Probably a bit of all of it. I choose to live with it.
As for a Duke game? Seeing that I'm ending my third year of officiating, and doing some smaller V, but mostly JV/F, if an ACC game pops on my calendar - even if it's Duke, color me there. I mean, I don't live in SoCal ya know!
