I think I can summarize this pretty easily...
Stability means nothing if your HC sucks...
I think Mike Schopp pretty much nailed the Rex-factor this week when he (basically) said we're supposed to believe Rex is great, and Rex's brother is great not based on results, but based upon the fact that Rex says so...
The Bills could very well blow the next hire too...But whenever Rex is sent packing, it won't be soon enough...
