Basically, NBA players - or rather this new generation of superstars - are a bunch of spoiled brats. They want to play with their friends, want the weather to be nice and to make the most money they can.
Boston has been a harsh town, one where grit, determination, hard work, all of that is concentrated. It's not the place where the flashy superstars go, it's where rusty old veterans go to win a title. Where you fight for the championship under the weight of 17 previous championships. You'll have to uphold a standard of sorts, which is unrivaled within the league.
EJPLAYA already mentioned part of the above (weather) but I think it's all part of a larger theme where the stars are just a bunch of kids with too much money.
Perk did well. He's not flashy, he's a frown. KG is hardly 'all laughs', Pierce has been through the grinder, Allen is the leagues hardest working sharpshooter and class act.
This is no place for the unmotivated, the cowering, the weak.
THIS ... IS ... BOSTON!
