Thanks to each of you for your analysis. I predict the player's range suggested in this thread is accurate.
At this point in his career, Nesmith seems similar to Jaylen Brown's rookie trajectory. A lot of physical talent that is getting refined with playing time.
Nesmith has one important advantage if you compare their second seasons on the team....Nesmith maybe patchy on defense and waiting for the NBA game to slow down some more, but he is a threat to become a top NBA shooter. Brown was never presented to us as a shooter.
This "might" help Nesmith this season and next, get to a starter's minutes even though the rest of his game needs work.
Nesmith's rookie year vs Brown's and Nesmith was a better shooter than Brown. Will this arc continue? BTW, I don't think Nesmith will ever be a better all round player than Brown, he has a shot at being a better shooter by a small margin.
Great problem to have for the Celtics!
