Colorado was decent because Deions name alone brought kids in. The thing that made Deion successful in college (recruiting), which is what 90% of college sports is about, is about 5% of what the NFL is about.
Now take that 5% and make it 1% with Jerry as the owner and not willing to sign free agents or trade for them and the #1 thing Deion is supposedly good at is now pointless. Because the final say on who comes to Dallas is Jerry Jones.
The NFL is about drafting, developing, scheming, having the right minds around you, culture building, and accountability.
Deion hasn’t shown to be good at any of those things.
This will be a disaster, but at least it will be entertaining.
