I think Rodgers was off his game ever since Buffalo. He just didn't play well for several weeks. All this talk about Rodgers being the best QB in the league - it's a joke. He was overthrowing and throwing behind receivers a lot the last few weeks. He was dominated by the Seattle D again today. If he didn't get a short field on several possessions today, the Packers might have been shut out.
Dominated by the Seattle D? I'll give that he was a bit off, although your reasoning for that seems a bit flawed and empty. Did you forget he's had a torn calf muscle the last few weeks? Do you have any clue how hard it is to even walk with a torn calf, let alone play at a level that keeps you in a game long enough to reach OT with what's regarded as one of the greatest defenses in NFL history? Sherman was lucky the ball was under thrown. No torn calf, and that's likely a touchdown. As for his other interception, lack of communication is likely the reason. He played far better than most would have. He was hardly "dominated" today.
He also flipped the field entirely on the first possession and brought us to OT in the final possession. I don't think you understand what it takes to be considered an elite QB, maybe you should adjust your standards a bit. When he's healthy, he's undoubtedly the best in the league.
