For the above, my definition of 'regular' was 1) still on the team, 2) at least 600 minutes played OR named 'Evan Fournier'. So 11: Tatum (+4.5), Smart (+3.5), Walker (+2.8), Brown (+0.8), Thompson (+0.1), Pritchard (+0.1), Nesmith (-0.2), Rob W (-0.8), Fournier (-1.0), Ojeyele (-1.6), Grant W (-3.2).
A bit different if looking at the cleaning the glass version of this stat, which eliminates garbage time and heave situations: Tatum (+5.1), Smart (+4.0), Walker (+3.2), Brown (+1.8), Pritchard (+1.3), Rob W (+0.1), Fournier (-0.1), Thompson (-0.7), Ojeyele (-2.3), Nesmith (-2.5), Grant W (-3.2). And just for fun: Mo Wagner (-39.4).
