Devyn Marble ... [is] deserving of [a] roster spot...
Marble was the most impressive Magic rookie against Philly. He scored 13 points on seven shots, including two from deep. He also grabbed five boards, recorded three steals, and dished two assists. He has a silky-smooth long range stroke and an impressive in-between game.
He's more naturally a guard, but he'll be playing mostly at small forward in summer league. He actually has decent size (6-foot-6) and length (6-foot-9 wingspan) for that position, but he's a little thin. Still, he's versatile enough to play small forward in stints and that will help his case moving forward.
He's going to make it in the NBA; trust me. :-P
