A few things I notice, for what it's worth:
1. You are playing some of your starters very heavy minutes, so fatigue may be an issue. I know it is hard to argue that Krell and Cook need more rest, considering that they are putting up big numbers, so I don't think you should cut back on their minutes. I'd change over to a slow tempo unless you are facing a team you should absolutely crush. That should minimize the impact of fatigue, given that you really do need those two guys in the game as much as possible.
2. Baker is not far behind Fermin as a PG, plus will return next year so you want to develop him. I'd probably raise his minutes a bit, helping him to develop for next year and making sure you have a fresh PG in at all times. If you're subbing by fatigue, make sure both of these two players are set on "fairly fresh."
3. I think Maher is better than Maus at this point. I know the shooting percentages indicate otherwise, but based on very small samples. They are similar offensively and Maher is significantly better than Maus on defense, so time to give Maher the second-team SG slot behind Jones. (Just keep Maher's distro really low until he proves he can score more efficiently, but meanwhile he will help some on defense.)
4. I'd consider starting Davis ahead of Wright at SF. I wouldn't play Doles at all, with his ATH and SPD he is the worst defender on your team at any position. I would even consider Tillman as a backup here, his decent ratings in ATH, SPD, and DEF mean he will hold his own defensively, and with his PER he'll even hit an occasional outside shot. I'd rather give backup minutes to him than to Doles.
5. If Davis ends up playing a lot of SF minutes, all the more reason to go slowdown tempo because that will leave you even thinner at the big positions.
6. Distro-wise, I would give Jones more of a share. He is easily your best outside threat, and when you consider his 63/45/80 percentages on twos/treys/FT's, it is clear that he could be a bigger part of the offense. If your opponent positions more inside in the second half in response to Krell and Cook, Jones may be able to take up some of the slack with his shooting.
Just some ideas, good luck!
