I know that Ben Braden has received some praise for his performance this summer and he gets some more from Trieu in a free article on Scout that talks about how kids from Michigan did during the camp season http://recruiting.scout.com/2/1083231.html
Regarding Braden, he writes:
When Braden committed to Michigan earlier in the year, he was still somewhat of an unknown. He had a good camp in Ann Arbor last year, and we had seen him twice in the fall, and he had earned offers from Wisconsin, Michigan State, and Syracuse. So we knew he was good, but he has proven to be even better. He dedicated himself in the weight room this offseason, adding good weight and getting up to 319-lbs. Even at that size, he was moving well enough to be considered a left tackle prospect. He's strong, technique is improving and he's more athletic than previously thought. He has a chance to move into the top 7-8 in-state and the four-star range when rankings are updated.
While the commitment of Magnuson and thoughts of Kalis, Diamond, Peat, Banner and Garnett have gotten a lot of attention, Braden is looking like an initially under-the-radar kid that could end up being a great prospect.
