I find the bench discussion interesting. Our bench is not that bad. It starts with Horford, probably one of the best bench bigs in the league. But you tend to kind of think of him as a 6th starter. After Horford of course, the bench drops off some but we have several players at multiple positions that I would categorize as "serviceable" or better:
Hauser
Pritchard
Kornet
Mykhailiuk
Stevens
Brissett
Banton
You may have Hauser and Pritchard as better than serviceable, that is fine. As it stand now, both would be expected to play regular minutes in the playoffs (along with Horford). As the 7th and 8th guys, they have some flaws or weaknesses but aren't that bad for the role. Then 9-13 or so, those guys are not expected to play in the playoffs much if any but as we are seeing, they are perfectly serviceable emergency role players off the bench.
I would say that Pritchard, Hauser, and Kornet are pretty much known quantities. They are what they are. They know their roles. They are probably not going to get much better, which is fine. The rest of them I feel are still kind of figuring out their roles on the Celtics and to some extent in the NBA. All of them could have some ceiling still. Horford will likely get 6moY votes.
