Charles Clay reminds me of the TE Andre Smith that played in Chicago & Dallas. Smith was a little bigger and a power house blocker that didn't get much opportunity to showcase his receiving skills much. They look & play alike.
It's been a few months & so far I'm sticking with my original prediction of EJ.
Right now I see us heading into camp with EJ, Tuel, a rookie such as Sean Mannion & perhaps a free agent that has at least 20 games in the NFL as a starter.
