With the understanding that Lean is completely trolling and there's no chance of this happening:
Blech. Not because Jay Cutler is a jerk (I think he's kind of like Vince Vaughn in Swingers where he's a good guy if you're his buddy, but he's an ******* if he's a stranger), but because 2013 is the last year of his contract, and he's due almost $8.5 million--$9 million if you include a workout bonus that he'll assuredly get.
Cutting/trading Kolb back would make the payroll a wash, but we'd have to take the entirety of an $11 million cap acceleration from past bonuses given to Kolb. That's $20 million of money in the salary cap at one position.
And then we'd have to work out an extension for Cutler, which would be in the ballpark of five years, $85 million, with something like $30 million in guarantees.
It's just not gonna happen, and that's why.
