You're kidding right... How many regime changes before this one where we saw the same reality, new coach new scheme new personnel to run new scheme.. Its happening again
The fact is Rex is supposed to be a great defensive mind. IMO that means he is capable of adjusting his scheme to the talent at hand. He did the exact opposite and tried to shoe horn his scheme in and we regressed massively because of it.
I don't know about you but I do not find that type of regression of defense palatable, all that does for me is prove without a doubt that Rex can not adapt, and in the modern NFL you either adapt or you are fodder.
I'll watch and I'll root for the Bills like always, but I saw enough last year to lose all faith in Rex and I fully expect continued heart ache and playoff droughts for years to come. Hope I'm wrong but I saw little last year that makes me confident in Rex.
