So we're going to score 93 points a game? Yikes. I can't say I disagree with that sort of total.
The most glaring issue I see with your breakdown is that Olynyk plays 6 minutes a game and scores 2 points a game. I just don't see it working out that way.
Name . . .MPG . . . PPG
Rondo - 32 - 13 pts
Bradley - 30 - 10 pts
Green - 36 - 18 pts
Bass - 24 - 8 pts
Sullinger - 28 - 11 pts
Olynyk - 24 - 10 pts
Humphries - 12 - 4 pts
Wallace - 20 - 7 pts
Lee - 18 - 7 pts
Pressey - 10 - 3 pts
Brooks - 6 - 2 pts
That's the same total of 93, with a somewhat different rotation and points breakdown. It's based largely on per-36 numbers for the players, with the exception of Olynyk and Pressey, who I guessed on. I guessed that Olynyk would score 16 points per-36, and that Pressey would score 10 points per-36.
