I am starting to think Vucevic is the play. Chicago got off to a hot start and was the 1 seed but they've lost 3 straight and are now the 6 seed. Regardless, Vucevic doesn't fit their long term plans and he's a rental this year who can probably be extended at a reasonable rate beyond this year (not a max-level deal). I could see Chicago flipping him at the deadline for some expiring salary + pick(s), which the C's can do.
He has his flaws for sure, but he's still a consistent 17/10+ kind of player and a nice scorer. And despite the age, I think he could absolutely be a nice player to have to help contend for the next 2-3 years AFTER this season. They don't need a superstar center, an above average to great one is perfectly fine. I also think he'd be more motivated on a playoff team with Jaylen + Tatum than toiling away with Chicago. Some people wondered about Porzingis' drive but he looked like a different guy with the C's when he was out there. And Vucevic is also usually available and not as injury prone.
And also don't kid yourselves. I like Queta a lot but he feels more like an awesome backup and fringe starter kind of guy. They still need a starting caliber center for beyond this season and Vucevic is that guy. I'm also not sure they have other options unless someone thinks Amari Williams or Tillman can make some miraculous leap. Vucevic consistently grabs boards too.
