Jerrah being Jerrah, wouldn't surprise me if he brought in Art Briles.Dallas…
I have heard Belichick and Harbaugh suggested. Of course, those are just rumors. Lincoln Riley (puke) wouldn’t surprise me either.
Here’s an intriguing idea, and not mine. How about Prime? While I can’t stand the guy, he actually might be a good choice for the Cowboys. Unlike at Colorado, he can’t easily disrespect, bully, or abuse the players. He just doesn’t have such leverage with professional athletes, so he might actually be an effective motivator to keep those guys focused.
