I think Adams and Furphy are more likely to play PG minutes than Solo. With Adams the case is obvious (as long as he adds a few pounds of muscle), and as for Furphy, he's probably going to be the best passer on the team from Day 1. And
Hurley certainly sees him as a guard, not a forward:
He'll probably be more of a Cam-type of secondary facilitator than a Tristen-type of lead guard, but everything I've heard and seen is that this is a kid who should have the ball in his hands as much as possible, and who's got a real feel for orchestrating the offense.
