Can't Millsap play SF? We've got 3 big guys that barely get minutes anyway.
Play Hayward and Miles at SG, and let some of the small PFs play SF.
That gives you 4 guards. They should manage 96 minutes between them.
Based on last night, I'd like to see Hayward getting a lot more minutes anyway.
Just give more minutes for Watson, Miles, Hayward, Evans, Fes, and Elson, shift a PF to SF some, and you're all set. Oh yea, and more minutes for Hayward and Fes, did I mention that?
If nobody else on the team can play SF , or Jeffers is better than Miles, fine, this would be my 3rd choice.
2nd option is just this: No reason why they can't try Hayward and Miles playing 35+ minutes each, for a couple games at least, if nobody else can play SF or SG well.
