This is a win win for everybody if it happens. We sign Martin to a vet min, if he rides the pine...So what? If he plays 10 minutes a game, awesome he'll be perfect, if he plays well enough to get 20+ even better. Id consider this a no risk only reward type signing.
He would be great in the locker room, has been heavily playoff tested, and is a great defender who will probably be even better alongside KG.
Also, if we end up making a bigger trade that involves Bass or Sully, Martin would be great insurance for us. Like someone said, he wants to play anywhere and is desperate, so he will probably be playing with a chip on his shoulder and give us some incredible intensity.
