At no point in time have I ever argued for a year to year contracts, heck I despise year to year contracts. I said the system baseball uses, and we are talking about a framework, not the actual system. With the NFL you would set the system up the way it is for incoming player, have them sign whatever contract you negotiate with them. Let's say you draft a running back, sign him for a 4 year contract, guaranteed(always guaranteed---another crime about the nfl system) but you own his rights for his first six years. After the contract runs out, it's an arbitration hearing, you submit a number(cannot be 20% lower than his previous year pay) he submits a number, an arbitrator rules.
