Maybe, but it doesn't matter. Either way, Correa was never taking the Tigers' offer, and the Tigers either knew that going in, or were too incompetent to realize it. Given the personnel of the time, it's 50-50 either way.
In any event, Correa's deal was not for not 2-something, but for 350. That's the amount he is guaranteed, so it's the only number that matters. AAV or not, he got all the money he wanted and then some. I think there's a good chance he won't even play the last couple or three years of the deal.
