I like Pritchard a lot. He already makes players around him better.
However, if his minutes and role stay constant he may not make an All Rookie Team (ART).
There are a lot of excellent guards out there. Even taking into consideration that with the ART selections they're often very loose with positions I still can see Pritchard fail to make one.
Lots can change over the rest of the season, but currently I could see this being the ART's:
First team: Ball, Haliburton, Quickley, Williams, Wiseman
Second team: Anthony, Edwards, Bane, Advija, Achiuwa
In that case Pritchard, Vassell and Tillman could be considered snubs, but the rookie selections are generally based more on putting up raw numbers than efficiency and contributions to winning.
