Agreed. We've been posting this for a bit now but I think the Celtics have two "needs" (neither of them are very big and one of them is more of an ideal scenario). This is kind of tangential to Queta because, in a perfect world, he could be the answer to the paragraph below.
I think they could use a big with some girth who can at least semi-credibly defend Embiid/Jokic without being put into the first row. Someone that can play 20 mins in the regular season and just save Al/KP from the wear and tear. Someone who's the big equivalent of a Hauser (basically Kornet+).
The other thing that could use some improvement, and this may not even be something that's possible with the new CBA, is strictly for the playoffs. Ideally, they would have a 7th/8th man that you have some more confidence in than PP and Hauser.
@HRB and
@Jimbodandy have been on this but I think it's really hard to trust PP in the playoffs. I just don't think he has the height and length needed to play without being mercilessly hunted.
