I don't think that is possible, since it sounds like it isn't what Rodgers wants. He wants guarantees that the Packers can't just cut ties with him when they feel it is best for the team. Which he should have negotiated for before he signed the last deal, but he didn't.
Yes, the Packers could say "OK Aaron, we get your point, we screwed up, lets do one more year and THEN part ways". I just don't think Aaron would be the guy who does that. He wants control of his future. I stated this last week but will say it again. If he wants control, offer him a totally performance based contract. If he has another MVP season, he gets paid like one, if he doesn't, he gets paid based on his year. He then holds most of the cards.....play well....you get rewarded. I would never want to see a team handcuff itself with guarantees that probably puts it into cap hell for 5 years, especially for a 37 year old acting like this.
