I don't doubt TE can get us to the playoffs, I doubt our O-line can protect him long enough to get a fair shot.
I think TE and Cutler both are partial victims of shotty O-lines, mixed in with sub-par WR's, and sprinkled with indecisiveness(?)...
However, if I had to choose right now between the two, I'd go with Cutler. He's everything most here complain Edwards is not, or does not have; guts, cannon arm, and the ability to give his WR's a chance to make plays.
