We don't have a roster spot now. Signing Gillepsie means waiving someone, either Lee or Misic. I'm fine waiving either but I don't think we need to make a move early. That also increases tax bill, which Ishbia has shown he cares about to some extent.
I believe we lose the matching rights if he is signed for the remainder of the year also, which would hamper our ability to re-sign him this summer. All so he could potentially play in 4-5 games. I don't think he'll make a difference in a playoff run.
He should be retained this summer but I don't see the need to do so early. The small positive, being eligible for the post season, doesn't outweigh the potential negatives. Those negatives being a higher tax bill and potentially losing RFA matching ability. We aren't making the playoffs, no 10 seed has. We definitely aren't winning in round 1.
I am in favor of JJ looking bad to finish the season so there's no chance he's retained. Gillepsie being off the playoff roster does that. Ideally, Gillepsie plays big and wins a game or two for us and helps us secure a playoff spot and then the Suns get trounced without him. Helping to highlight why JJ needs fired while also signalling to the new powers in charge that Colin needs signed long term.
