The Aggy brain-trust (I use that term loosely) who signed Jimbo to the insane contract clearly did not perform some of the most basic risk analysis before doing so.
A simple 3-part question like, "If we need to make a change after year X, what will it cost us, will we be willing to pay it, and will we have the cash?" In a real business, if the answers are not "we know, yes, and yes" then you do not proceed with the contract. For Aggy, the answers are "holy shit, maybe, and no." I think. that was the answer when the signed him and it is definitely the answer today, esp. if you have legally minded Aggys looking for reasons for cause. Actually, when signed, the answers were likely, "Don't care got Jimbo; Don't care Got Jimbo; and Don't care got Jimbo"
We all believe a contract like this is foolish. If you willing to eat the political shit-sandwich and pay the cash, then the contract was "fine." Risk/reward/etc.
Don't forget that Jimbo was the 2000s version of BoB. His name showed up as a candidate for EVERY OC and tier-2 HC search. Perhaps Aggy believed a 10-year deal was the only way to secure him.
The question Aggy needs to be asking themselves at this point: is it worth it to pay out the entire contract to get rid of him? Short-term pain for long-term gain?
When a CEO is fired by a board, this is one of the questions they ask. I am fairly certain the board concludes, "Yes it is worth $80+ million to get rid of that person" once the cut ties. Aggy needs to answer the same question.
