goose - If I were you i'd change your lineup a bit. I'd set my depth chart as follows:
PG - Kimball, Treadway, Taylor/Crabtree
SG - Treadway, Barragan, Taylor/Crabtree
SF - Gallegos, Ronning, Kimball/Crabtree
PF - Ziebell, Denton, Ronning
C - Mancia, Hayes, Ziebell
My reasoning is as follows:
I ALWAYS want my player with the best BH/P/IQ combo at PG. Kimball clearly your best PG. I know you want to play him at SF because he can rebound, but he's your best PG. Treadway can slide over from SG and Crabtree/Taylor from there. Crabtree, to me, is a backup PG right now because he's limited offensively but he can distribute okay.
Treadway is your best SG even though he's a defensive liability. If your opponent has a lethal SG, I might bring him off the bench and start Gallegos, with Ronning and then Barragan at SF.
I like Gallegos as your starting SF. SFs tend to get a lot of distribution, especially the SIM ones, and he's your lock down defender. Ronning isn't bad here either because of his rebounding ability. With Kimball, Treadway & Gallegos starting you have some nice ATH/SPD on the perimeter, which is crucial for a press.
Ziebell and Mancia are your best bigs, but you know that already :-) I would up Mancia's distribution a bit though. He's not going to kill you by shooting more and he's okay from the foul line too.
Overall, you are a little thin with your big men, in particular LP. Fortunately you have guards that can take it to the rim, so you can have them either shoot 3s or go to the basket depending on your opponents tendencies. I'd also not run uptempo and stick to normal tempo unless you clearly outclass your opponent (you may be doing this already). Good luck!
