I think Coffman will be okay. As has been said, he's doesn't have the tools of Freeman, but I think he's a great decision maker and has really picked up the progressions in the passing game. Coffman is listed at 6-2, 200, so he's not tiny. One of the coaches said he was up to 210. He looks small, but then again you are comparing him to a 6-6, 250 pound guy out there.
The Freeman offense also has the 2 most consistent recievers and our best TE. The Coffman offense has Johnson and Mastrud. I think it will be interesting to see how they do. As I look at the rosters, it looks pretty balanced to me. I think it could be a decent game.
