Well you are right, I can't be sure. I just don't recall any plays in which Aaron treated them as a free play, when there was no penalty. Regardless of the outcome. This is the first time I remember that happening. And I watch a lot of Packers games.
I think the calf affected his mobility and footwork, sure but I do not believe it has that drastic of an effect on his accuracy. He was more accurate and efficient vs Dallas and Detroit and did not make the crucial mistake, in spite of his injury. Yes I know Seattle's defense is tough, but I still watched the game and saw errant throws to OPEN receivers, mis reads, and poor decisions that didn't appear to be affected by a pass rush or suffocating coverage.
What I saw was Aaron playing a crappier version of his typical playoff game, which sadly enough isn't good enough to beat good teams.
