Huh? He's currently the Bills OC. His only negative stint was with the Panthers but everyone outside a few purple and gold homers knew Brady was nowhere near ready to be an NFL OC at that time. He's since learned and grown with the Bills as their QB Coach to Interim OC to now official OC of the Bills and they were the #6 scoring offense with him last season and #2 in scoring this season. He also just annihilated Aaron Glenn who a growing number of people want/think will be the next Saints Head Coach.
That said, I still go all-in on Ben Johnson. Johnson has a far more impressive resume and I think he's got what it takes to be a great Head Coach.
