Ainge's latest move comes as a shocker and makes no sense right when you're ripe to make another championship run, giving up two warriors like Perkins and Robinson. Believe you me, I've watched Krstic for a long time when he was with the Nets (my local market) and he was decent and average at best -- very serviceable but not someone you can count on in big and meaningful spots, especially on D or boards. He's not tough or gritty like Perk.
Anyway, forget balance of power shift from West to East... I like the total shift now happening for certain from Boston to NY
