Sallis can play the 3/4.
Puff can play the 2/3
Ingram can play the 3/4
Leaky will be a Senior
Roy loves to play a bunch of players and would excel with a interchangeable lineup with those group of guys.
I believe Sallis is more of a combo guard, possibly recruiting him as a PG. I see Puff as more of a 3/4 at this point. Ideally, Roy likes to have two ball handlers on the floor at the same time. Puff will need to get stronger, but he certainly has the length to mix it up down low a bit.
