Thibs has overplayed guys, but the team does have somewhat a history, at least from the front office side, of pushing minutes limits (Pax vs Vinny). I think the Bulls would put Rose on a strict minute cap, even if there was an OT. Maybe Rose realizes Thibs does exhaust players and didn't want to have to tell him no and sit out in key moments. But that's why you play the last three weeks of the season and build your minutes up. Or maybe Rose is just mentally weak.
