This is where I'm at - I too missed the game, but if you had told me beforehand that Ajayi would run for 200+ yards, I'd have predicted an even bigger loss. What I want to know is what the issue was in run defense. They're light on talent, for sure (Corbin Bryant has been quietly awful all year), but usually you can scheme to stop the run, and Rex especially has been good at this over his career. It looks like they played yesterday with Mike Pettine's defense from 2013 and Chan Gailey's offense from 2012.
In any event, putting aside the really tired crusade by Major General Jerkoff, if Tyrod doesn't start throwing over the middle with anticipation than he'll be benched, if not this year, certainly next year. End of story.
