Bersin is tall (6-3) and a pretty good blocker. He ran a 4.58 40 at his pro day. He catches over the middle, outs, digs, --probably no deep routes, but he can play. Imagine him with Benji and Olsen in the red zone.
I think he is perhaps labeled because he is white and is not taken as seriously. The special teams comment is valid, but I think he is a bigger version of Proehl.
