Steelers coach, tomlinson, has had big ben his entire coaching career...giants tanked coughlin after a bad year..not the 2 best examples to use. Rex was successful his first couple of years with the jets because he had a good o line and a stellar d..he poached some good talent from the ravens as he knew them. His offensive game plan requires a good back and a good o line, and without a good d any team is sunk, and i don't think he has had any of those since his first couple years with the jets. I also think he benefitted from being a new guy, and his bluster worked on that team for 2 years, then it went downhill, quickly. I think he need to take on a DC role somewhere, that would be his strong suit.
