That figure is at its current rate. This entire thread has been about what they will do to RESTRUCTURE the contract, so the salary number is reduced, while giving him roster bonus/playing time incentives to recoup much of that $$$$. So that ranking is irrelevant.
I agree with you regarding the extension, and building in future protections in the form of roster bonuses as a way of protecting the organization in the future.
My entire point all along, has been they don't seem to have a problem with paying him the entire total of the contract, provided he is healthy and ON THE FIELD. Regardless of how the fan base feels about what he has "earned" or what he is "worth" in their eyes, the $12.9M is the number that he is "owed" from the contract, and IMO, would be the target of any incentives that are laid out in any restructure.
They are unlikely to guarantee any future $$$ if not part of a roster bonus based on health. And when that happens, they will also have to take into consideration the cap hit in 2016 assuming he received the incentive $$$ in 2015.
