None of the players I'm interested in I would qualify as scrawny. They're thin, because they're very long and young, and at that age most young guys who grow rapidly need to gain muscle mass. But they've got the frame to put on the weight, I'm not the slightest bit concerned with Daniels or Sochan in that regard, like I'm with Chet for instance (who I think will always be pushed around and prone to be injured).
The shooting I will concede, but again, I think it's easier to improve your shooting that to make a selfish guy pass, a stupid guy think, or an untalented player gain skills. So given that every guy in that range is lacking something (that's why they're there after all), I'd rather target the guys that have those traits you can't teach and bet on them adding the shooting that's missing. If they become even adequate, they're going to be really good pros.
