Deron
CJ
AK
Jefferson (or possibly Millsap)
Fes
I'd give Fes about 15-20 minutes per game, and give the rest to Sap/AL. I'd give Hayward and Evans significant burn, and reduce Bell's minutes by 75%. I'd also find a way to unload Okur, and possibly AK (even though I'd ideally like to keep for 5-6m a year).
I would take advantage of mismatches, and go with whatever lineups work at the time. Instead of random robotic substitutions and plays.
I would play Deron at the 2 for 10 minutes a game, with Watson at the point.
I would have no problem with someone losing their starting position after an injury, if someone else steps up.
