I don't begrudge Ray going to Miami. Their play style not only fits him well but will also serve to prolong his career.
That said, I don't think the drama in Boston had much to do with his decision. Ray is a professional. He's been through enough in the business not to take things personally I would think. Rondo acting like he's the big dog on the team may have something to do with it, but I doubt coming off the bench affected his decision, seeing as how he was benched due to his injury issues. Nobody in their right mind would expect him to defend all the starting 2 guards in the league, neither should he have to with his ankles, and with Avery Bradley in the team Boston made the right move. The trading block thing doesn't make sense either. All of the big four were available for a trade if the right offer came along, not just Ray.
I don't see this as Ray not wanting to play for Boston out of spite, it's not like the Celtics did him dirty, this was simply the best situation for him.
Also, lol at Rashard Lewis being a difference maker.
Can't decide on a signature? Why not Zoidberg?
