Well, tbh, I am a little hesitant to add guys who EXPECT to play major minutes. We've seen a Celtics team completely fall apart do to playing time issues.
More to the point, it doesn't really matter what any of us want. The team is projecting to be 20+ million over the tax line, and they are pretty unlikely to keep stacking salary beyond that for end of bench guys. And I'm fine with that, they spent what they should spend for a contender.
Most likely they fill out the bench with a vet min center, a couple of their second round pick guys, and go from there.
