Not a capologist "if that is even a word" by any means, but the cap for the NBA isn't a hard cap like the NFL is it? It seems like the Knicks are spending way over the number and just pay a premium on the money over the cap. If this is just a luxury tax issue just pay them both and keep the ball rolling. Lets live in the moment. I doubt ticket prices, food prices, clothing prices or any other Celtics related revenue are going down in the next few years so I don't see how as a fan any of the cap issues effect us.
Pay the man...
Well, there's a soft cap in the NBA because teams can use "exceptions" to go over the salary cap. You pay the luxury tax if you go over the cap but you can't just sign who you want the way you want even if you don't mind paying the tax.
So,
the C's can't just offer Posey a $13M/2 years contract for him to stay, because they'll need cap space to do that. Nothing to do with the luxury tax.
On the topic, I agree with Roy on House: if we want to resign him, the non-Bird exception or the LLE will do it. I'd rather use the non-Bird because that would allow us to use the LLE in the FA market if needed.
Posey is a more difficult case. We don't have to worry about above-MLE offers because teams with cap space will spend it on more valuable free-agents (Brand, Arenas, etc). But I assume that at least one team will offer him the full-MLE for 3 years - $18.5 million for 3 years.
That'll leave the C's with 2 options:
a) match the offer. If we do that, we won't be able to sign new players, unless using the LLE (bi-annual exception) and minimum salaries, for at least the next 2 years. I'm not sure if I want to keep Posey this way. Too risky.
b) offer him a 5 year non-Bird contract. That'll be a much better option for the Cs. For Posey, it's probably worse, but there's a chance he'll buy it: if he accepts this offer, he'll be making $22.5 million in the next 5 years. In 2011 Posey will be 35 years old. Does he think he can make a $4m/ 2 years contract at that time, to match the same amount of earnings in a 5 year span, assuming he chooses the 3 year full-MLE now? Does he intend to keep playing until he's 37?
