Three things:
1) It would be amazing if CP3 pulls Elton Brand on Sterling.
2) I think it's great deal for both teams. Celtics aren't going anywhere with the current roster. I think that first round exit is the best they can hope for next season. They got bad contracts, aging roster that won't get any younger and the things can only get worse (btw, you can say the exact same things about the Lakers at the moment). That way, they will get rid of two terrible contracts and will get a young, athletic Center that can be perfect next to Rondo and two draft picks that they can turn in to nice things. Don't forget that Davis, Perkins, Jefferson and Rondo - all Boston draft picks.
As for the Clippers, it's pretty obvious. Their goal is the Championship. Right now, they aren't close to it at all. Griffin's attitude is terrible. He is the same as Howard - prefers to clown off instead of getting serious. To be more accurate - unfortunately for Clippers, it's the only similarity between them. Dwight is amazing defender and shot blocker and he can take over a game. Griffin can't do almost anything expect for highlight moves and flops.
I really expected him to have much better mid range jump at this point - something that he just has to add to his repertoire.
KG can be a mentor to Griffin (or he can kick his ass if that won't work) and Rivers actually knows how to get the players to play for him - both are winners and should bring some "bad" in to this team.
On top of that, CP3 wants them and no draft pick or Bledsoe worth losing CP3.
That brings me to the third point:
Boston has Clippers on their knees. Sterling has to be crazy not to sign off on this deal, even if it means to give Jordan, Bledsoe, two draft picks and take back KG, Terry & Lee...
Why on earth Boston backing down?
Also, why two teams that have potential HOF point guards in their prime, fight so badly over very promising, but still, only back up point guard???
