Is it your contention that Rodgers was not missing a beat those two years?
Factor in that Rodgers was playing injured during both of those years. His mechanics had gotten so bad that it appears he'd lost his touch. What I may have considered differently than most people is that Rodgers has always been a student of the game, and the same way he learned, and improved on his mechanics when he came into the league led to his success. I figured he'd be more than willing to spend an entire off season quietly working on them, to get back where he felt he should be. He did exactly that.
Nobody should be faulted by not seeing that he could regain his form. There was always the chance that he'd never return to his previous level of play. I've seen it in QBs, and if you want a baseball analogy, even more often with pitchers in Major League Baseball. A slight change in mechanics, and everything you've been doing successfully for years disappears, as if flushed down the drain.
The problem is, people need to see that what he has done over the last two years is really pretty darned good. You don't win two MVP awards, which is a distinction that comes from people who watch the game very closely, and vote appropriately. As for Rodgers winning it this past year, he did so despite the fact that a heck of a lot of the voters thought he didn't deserve it for reasons outside of football, and voted accordingly, for Brady it seems. An example would be Arkush, who would have voted for Love, over Rodgers, if he had to choose between them. How many others felt like him, I don't know, but Rodgers even exacerbated that problem by calling Arkush a bum! Not smart, if you're looking for votes. Still.... he won the award.
I see something driving Rodgers. He has 4 MVP awards. Only Peyton Manning is out there, with 5. I think Rodgers wants that 5th, and would stay two more years to get it, if possible. If he got it this year, he'd probably stay through '23, if they wanted him, to try to get his 6th. He wants to ride off into the sunset with the personal awards, since the Super Bowl championships have eluded him.
Anyhow, that's my opinion.
