We dont need contracts that are going to handicaped us salary wise especially while the big three are here.
But the Big Three being here automatically means we're financially handicapped as they consume the entire salary cap by themselves. Thus, as long as they're here, we will
never be below the cap.
Thus, the term "financially" handicapped all depends how Wyc feels about paying the luxury tax. If Wyc is convinced that he can make money (or at least break even) on paying the luxury tax because of the deep playoff run and funds generated by success, then keeping Posey around at
any price--so long as his contract is done when the Big Three are done--does not hurt the Celtics at all.
The only way re-signing Posey potentially hurts the C's is if it's a) a long contract beyond the time that Ainge plans on keeping around the Big Three (keep in mind, that isn't necessarily the end of their contracts, he could extend any of them) or b) if Wyc's pocket is not infinitely deep.
But as far as rounding out the rest of this roster, guys like Eddie House and Tony Allen are minimum guys or can be replaced by minimum guys. Similarly, someone like the Birdman will probably come here at the LLE. Remember, Boston is now a destination to play, this isn't 2006 anymore.
As far as the Scalabrine idea, that's just crazy. The guy couldn't even crack the active roster in the playoffs; there is no way he's going to take Posey's place. He can't guard 2/3s well and he doesn't hit the three nearly well enough to be an effective weak side shooter that the C's need on the court to get spacing so defenses can't cheat off the Big Three.
