I'd keep escamillia under wraps and play peterson as the backup SG, might not be real life, but senior near 800 level guards tend to contribute far more than 600 something frosh SF's,
after that, it is worth experimenting, since if you get it right, you have a shot at winning it all
near impossible for anyone to tell you how to play them, so much depends on shot selection, distro, pace, etc, there are schemes I use where davis for sure would be my PG, others where I would not hesitate to play him at SG, just depends on how you want to approach things -
