I like:
PG- Fowles, Koehler, Dickens
SG- Fisk, Dickens, Koehler
SF- Harrison, Chalk, Peters
PF- Kemper, Willis, Hayes
C- Meyer, McCambridge, Hayes
I started Harrison over Dickens because of defense. Your team is hurting defensively. Your 5 freshmen have an average DEF rating of 24. I hope they all have high potential for defense.
I'd flip-flop Fisk and Harrison at SG/SF, letting Harrison guard their best offensive weapon. I'd do the same thing with PF/C, letting Kemper have the toughest assignment.
It looks like you didn't redshirt anyone. I recommend always redshirting, using your best prospect, unless you desperately need him immediately
