I think Sean Payton would be the only coach that could repair the Rams offense. He will get rid of players he thinks are slacking and not giving their all. He coached Marshall Faulk in college and will know if Gurley is the answer at RB. I don't think he will waste time on Gurley if his knee, lack of preparation and ego are the problem. He won't let Todd Gurley become a prima donna.
I think Payton would trade for Tony Romo during the off season like he did for Drew Brees to bridge the gap for 3 years while Goff is developing or if they draft another rookie QB in the next couple of years. Plus Payton coached Tony Romo in his rookie year. Jerry Jones will want to help his buddy Kroenke by trading Romo for a late round pick.
