Not sure what to do with this, but, here goes.
PJ Dozier appears to be on the roster today. I'll assume he stays this year, but, maybe not...
Dozier 6'6" 205 lbs - Maine FG 46% 3pt 31.2% RPG 6.6
Dozier ------------- - college FG 40.7% 3pt 29.8% RPG 4.8
Romeo 6'6" 215 lbs - college FG 44.8% 3pt 27.2% RPG 5.4
I just don't care much for what happens in G league, but, Dozier hasn't played in the NBA enough.
Anyway, these players have "general" similarity and Langford might offer a good "arc" entering the NBA.
This, I assume, is why Ainge picked him and, yes, as has been stated? He will need to "arc" the three point % up to get minutes.
