The Pistons could use a defensive-minded big man if they’re truly committed to making the playoffs this year. I think they’re more committed to minimizing costs, even though they have the full mid-level exception to offer.
On Dampier’s end, the Toronto Raptors were supposedly his second choice, so he’s obviously not completely attached to playing for a contender.
The odds of the Pistons signing Dampier are still extremely low, but they’re higher than they were a day ago. With Greg Monroe’s strong play lately, do you even want Dampier anymore, anyway?
