He will need a little weight room work like a lot of people, But I don’t think he is all that puny. He’d project as an NBA two - so guys like Hawkins, Bouknight, Reed Sheppard, Tyler Herro, etc. have the same build. SGA is a little bigger, but not much.
In college, the 2 and the 3 are close to the same thing in most systems offensively - we could throw back to the days of Rashad and Ben on the wings and tons of spacing. Defensively, maybe you run into a 6-7 bully ball type he’d struggle with, but we have Demary now … and Solo has good upper body strength and could take that type of player, probably easier than a shifty guy who tests his lateral quickness.
Smallest of sample sizes, but Dybsantza bully-balled Mullins and scored (one play after Mullins picked his pocket and scored on him). But I kinda thought Mullins played it pretty well. Took a shoulder to the chest and stood him up and didn’t get knocked backwards. But then he didn’t contest the 8-foot jumper. Sorta allstar game defense. But it wasn’t like he was manhandled or embarrased. And then a couple plays later Peterson tried to attack him on the perimeter and he locked him up completely - but that was more of a foot speed thing than a strength thing.
Towards the end of this reel. I misremembered a little. He was trying to contest but it was a spin move that got him. But watch him absorb the contact a couple times first.
