Hiring someone like Deion will only prove once and for all where Jerry's priorities lie. If the focus is on trying to win something you look at a Ben Johnson type. If the goal is to keep the circus atmosphere rolling along you bring in Deion.
Personally, after 52 years of being a fan of the Dallas Cowboys, I think I may have finally reached the end of the line. Depending who Jerry brings in I might find myself at the breaking point. I might finally reach the point where I say "I hate the Dallas Cowboys", and the only person to blame for it will be Jerry friggin' Jones.
Hiring Deion could end up being the worst HC hire in the history of the NFL. Worse than Jason Garrett, Chip Kelly, Steve Spurrier, or Urban Meyer
