We did this with Dak's extension. Dak made 75M in 2021. 66M was signing bonus. Thats a ton of cash up front.
The problem is the Jones boys are so football ignorant, they don't know who to bet on........ this is particularly true outside the organization. They aren't going to go out and make that "cash over cap" bet on players they aren't familiar with ..........which is most all of them. If you ran into Jerry or Stephen in a bar and asked them to name the starting defensive unit for the Denver Broncos or Balitmore Ravens, they couldn't do it. While Les Snead could probably name every player who wore a jersey in the NFL last year and every teams current practice squad.
This is the inherent problem with not having a legitimate dedicated GM.
