Ray Allen left the Celtics behind this summer. You could make the case that he was preparing to do it long before then. I don't question the effort he put on the court, I just think by the end he knew he was gone and that was all there was to it. Regardless, he's moved on completely at this point. You can just tell from his words.
Allen on C's: I have a bond with them - Boston Celtics Blog - ESPN Boston
Allen said his ankle is now about 75 to 80 percent healthy, and he expects to be 100 percent when training camp starts next month. The Heat will open the season against the Celtics. "I look at the guys I played with five years," he said. "I played seven years with the Bucks and four with Seattle, so at some point you're always going to have ex-teammates. But winning [a championship] with the guys in Boston, I have a bond with them. It's going to be a special game, though I am not an emotional person."
I'd wish him good luck, but that would be a bit disingenuous. So I'll settle for wishing him and his family all the best off the court down in Miami. I hope he has a fantastic time doing what they do best there: golfing and retiring.
