He should certainly be brought back again next summer. If Richardson wasn’t signed he might have been kept around to play in Maine, but he’s not an NBA rotation player at the moment unless you consider Nesmith an NBA player.
Nesmith needs that developmental time here and Begarin is playing 25 minutes a game in France. If he were in Maine he’s probably working more on his 3 point shooting though. He seems to be playing his usual Westbrook style game, which either means his coach wants that or he doesn’t care to work on his outside shots.
