There is something about seeing Ray Allen on the court that makes me feel calm. I know he's not all he used to be, but the respect he gets is still a factor in spacing the floor and opening up defenses. And until he proves otherise, there is no one in the NBA I'd rather see heaving up a last second shot that Ray Allen (Kobe's recent heroics notwithstanding).
That said, the OPs trade idea is exactly the type of home run ball Danny should be looking for. If Danny has a chance to make the team a little younger and more talented in one fell swoop -- he's got to do it. But I sure would miss Ray.
