They have to add a center that can start.
Move Hauser and let Baylor and Hugo assume that role. Both should be in the gym shooting 1000 3s a day.
They still need guard depth.
Who would you target at center?
No love for Queta? Idk - he looks like a starting center to me.
I guess it depends on what your definition of starting center is. He was a net negative in the playoffs. Seems like something they should try to improve upon rather than crossing their fingers and hoping he continues to develop.
Queta is fine, they just need another guy to pair with him. Like an actual playable big man in the postseason, not Vucevic or Garza. Garza is alright just eating up spot minutes but I don't think he's a true backup big either. Even if you added a Claxton or Wendell Carter-type with Queta and each of them went 24 minutes per game, that's fine.
Me personally, I'd try to add two guys. Trade for someone like Gafford/Lively/Claxton/WCJ and then sign someone with the MLE like Porzingis, Timelord, Nurkic or Mamu. Revamp the frontcourt, but in essence just have a better rotation and mix of guys that can alleviate Queta's role. It became clear Vucevic was toast in the playoffs, but then with Queta also getting in foul trouble fast he couldn't go heavy minutes either.
Baylor, Hugo and others can still help out the guards/wing spot, but the frontcourt needs more. I personally thought the two biggest issues in the series (besides the 3-point Mazzulla philosophy) was White being bad, but also the frontcourt situation looking hopeless. And guess what, the league is trending towards those guys too (Embiid, KAT, Wemby, Jokic, etc.), you're gonna need to beef it up more and add size to combat it/neutralize it. Relying on smallball to cover those guys like the C's did in Game 7 vs PHI is tough.
