Not sure the Steelers would have signed or brought him in over Fields but in my opinion, he would have been a better choice.
In Pittsburgh the QB doesn't need to be all world just average. And right now, Russell Wilson isn't even that. Last week we don't even score a TD, however our kicker makes 5 FG's and our D does what they are going to do.
Last night after the first miss Tomlin got nervous which he shouldn't have and ends up trying stupid 4th downplays at mid field. Kick the ball and pin them back and play what you want and always do which is Field Position football. Instead, we don't and end up losing that is part of the frustration.
