That’s kind of wild to me. What does a better deal look like?
Neither Vuc nor Coby are worth trading for. You'd be doing the deal for Williams, #18 (Agbaji, Jovic, Liddell, Terry?) and a future late 1st. That's not a good enough return for Gobert, imo.
A deal with a top-10 lottery pick or multiple young players like Collins/Huerter, plus a mid-1st would be better.
