Not really, summerleague tells you who can't play, not who can.
This is a perfect one-liner about summer league. I've seen the sentiment before, but never this exact explanation, and I think its awesome.
Guards I like from 2012 Draft:
Lilliard: Everyone pretty much has said whatever there is to say about the kid, so I will leave it at that.
Jeremy Lamb: He's never going to be an iso-beast like Kobe or Wade, but he's got more athleticism than Reggie Miller ever had. As long as he works hard, he should be a healthy mix between Rudy Gay and Reggie Miller, with the athleticism to wow you on some night, but the sweet shooting stroke to keep him in the elite levels of SG's. I think he's a top 5 Shooting guard within 4 years.
Tony Wroten: This guy is a little experience and consistency away from being a star. He's the Avery Bradley of this draft class, except he's way more dangerous. He's 6'6, a far better passer than Bradley, and better at getting to the hoop. He had a rough freshman year, but I have no idea how he fell so far to Memphis.
