I got turned off by Vuc during playoffs. Totally shut down by old timer Marc Gasol.
Julius Randall? Love his energy, but if his defense is half as bad as his defensive reputation, I would pass.
Russell would require a huge salary. Plus I don't normally say this, but he just doesn't strike me as a Celtic. Something very selfish about his play. I don't deny his ability, especially last season, I just don't think he would fit chemistry wise. Need to let the team leadership emerge from Smart, Brown and Tatum. Adding Russell just feels too Kyrie - like.
