According to Woj, it sounds like Pat C is opting in for this season so he will be back. Good news for the Bucks. Could be a sign that they extend him later this summer.
As for Tucker, I’m not sure it makes sense to get him. He wasn’t much of a factor for Miami against Boston, and as you pointed out MP2 the Wes Matthews signing was just as impactful for a lot less money.
Personally, I think you’d be crazy to sign him to a 2 or 3 year deal given his age and the fact he’s not playable against every team.
