The Ragland situation puts all the spotlight of Rex and Rob and their "great" defensive minds and schemes. If it is half of what they think it is, the Bills will be alright. If its is like last year and the D takes another step backwards, Rex will be exposed as an impostor, or at the least he'll become an afterthought in which the NFL that has caught up to his "great" schemes, and passed him by while he wasn't even looking. Time will tell.
As for the 14 ranking, I think that is fair. We're close, with a break or two, and progress from Taylor and improvement on Defense, the Bills can make the play-offs. And to state the obvious, if either one of these digresses, we will be worse this year.
