I went back and forth on BW all year.240 - 35 for JT
205 - 35 for JB
170 - 35 for Kemba
135 - 35 for Gord
100 - 35 for Marcus
65 - 28 for Theis
37 - 15 for Kanter
22 - 12 for Wanamaker
Leaves 10 minutes to be either divvied up between the players listed above or sorted out between the rest of the bench.
I see Wanamaker getting minutes for Stevens. He's averaged 19 minutes per game this season, is high effort and plays within the scheme. I see him delivering neutral minutes at worst, i.e. what you hope to get out of a 5th starter in MLB.
In most matchups I think that he's fine defensively. He's backing up Kemba, who isn't Pat Beverley either. But very quick guards do feast on him, worse than anyone else that we have. So I suspect that he'll also have some games where his minutes are limited by that. Quicker hook in the playoffs seems more likely than the regular season. Depends on who we face.
Regarding Theis foul trouble, I just don't think that's a thing to worry about. If it happens, the other wings and GW will cover some minutes.
