Based on the assumption that (4) of the starting (5) next season will be Tatum, Brown, White, and Queta (as things stand now), the question then is who is the 5th starter. Last season those (4) + Hauser played 153 minutes over 13 games and had a NRtg of +6.1. Those (4) + Pritchard played 50 minutes over 11 games with a NRtg of +46.4. There are no minutes with Simons and this core group of (4) starters.
Vucevic-Tatum-Brown-White-Pritchard had a NRtg of +44.7, but in only 12 regular season minutes. Vucevic-Tatum-Brown-White-Hauser had a NRtg of -75.0 but in literally only 1 minute of court time. Vucevic and Tatum only had a few games in the regular season where both were playing. In the playoffs, Starters+Vucevic+Pritchard was +19.6 NRtg (34 min) and with Hauser it was -19.9 in 27 minutes.
This seems to support premise that a ball handling 5th starter is better than a purely shooting 5th starter whether Queta or Vucevic as the big. This is a small'ish sample size but enough to mean something. I tend to agree that the team is better served by having Pritchard off the bench. In my mind, that applies to Hauser also.
