How long do fans hold a grudge against those who take away their teams? A long, long time

It's been hard for Seattle SuperSonics fans to watch the NBA Finals, with the transplanted Oklahoma City Thunder. Just four years after losing their team to Oklahoma, Sonics fans still hold a mighty grudge, and photos of owner Clay Bennett and former owner Howard Schultz would be on dart boards all over the Coffee City ... if fans could even bear to look at them. But don't expect those grudges and feelings of hate to just fade away any time soon. Fans from Cleveland to Brooklyn, Los Angeles to Quebec City and Minneapolis to Atlanta can vouch for the fact the ill will stays a long, long time.
