I think Grant Williams will be playing in the NBA for a very long time.
But I don't think using GWill as a Center is a good idea.
Celts will not win a lot of playoff games if majority of his minutes are at Center.
I think that the results are not too bad - encouraging, in fact, and amazing when you consider that he’s undersized and a 21-year old rookie.
You’re right to point out that the playoffs are different; if he’s going to be effective in that role he’ll need plenty of reps in the regular season.
Interesting
when they have him doing it: very often, to close quarters; in the Orlando game, finishing the 3rd and opening the 4th. The team was +4 in those minutes, fwiw.
Also a fascinating insight into the coaches’ thinking: in those minutes he was paired with Ojeleye, who is almost exactly the same weight and height, and shares the same lack of great length. Playing these two together has been going on since pre-season, off and on but frequently.
