I could be wrong, but I don't think that PG can sign an extension and be traded, and even if he could sign an extension, would be severely limited in the raise he could get. Larry Coon's faq says that a player cannot be extended and traded in the last year of his deal, or what could be the last year of his deal.
So if we can't get PG under contract before or at the time of an Indy deal, we'd be dealing for him on blind faith.
We're giving up a #3 overall pick for a guy who has been telling anyone who would listen that he wants to go to LA a year from now. The same time when Lebron will be free to go to LA with him.
ainge can't do it. The minute he does the deal, he has no leverage, no anything with PG. Would be almost as dumb as NJ giving us those picks to begin with.
