TP for you TripleOT; Pat Riley made that mistake, and we should not risk this, seeing how Posey has been an integral part of the Celts this year.
I say let's take a chance and give him the Full MLE, but not without trying to persuade him to take less. Actually, this is so frustrating, because other teams will offer a lot.. This is a semi-lose situation no matter what we offer, as it decreases the money we have left to spend. Knowing what he did in Miami by leaving for more money, I think we should offer him what we have, and let him either take it or leave. It also depends how much Posey wants another ring, and what he thinks of this team.
BTW, I'm not impressed with Sam at all, but he does come cheap. Another shoot first PG isn't really needed right now, given his inconsistency and age as well.
Also, I doubt TA will receive any other offers that the Celts can't match. He's been pretty under the radar, for good or bad I don't know, throughout this playoff.
