Mags really plays his cards close to his chest.  I'd like to think that if the offer was made to him, he'd resign with the Blazers (he has said that he likes Portland), but realistically, he will probably sign an MLE with a contender.  Unfortunately, the Blazers are still 1-2 years out from that and I'm not sure if he'll want to wait until he's in his 30s before having a reasonable chance for a ring.

However, as my wife points out to me frequently, I've been wrong before.
