A_3PO and others are right when they point out how the Heat need drastic upgrades at PG & C rather than more perimeter defense. Adding Shane? Unless it's for the vet minimum and requires allocating next to none of their limited resources to acquire him, I agree this is poor idea.
I think Shane would be good for them. But, I think he returns to Memphis. Besides, I think even more useful to the Heat would be Chuck Hayes. He'd help with the interior defense and rebounding. Smart player that doesn't take away looks from the Big 3, but isn't an offensive liability anymore either. If they have any money this offseason to spend, I think that's the guy they should get. Without Adelman here and a total roster overhaul a real possibility, I can see him as wanting a change of scenery.
