I, too, hate the "beat ourselves" line.
You lost. You played like shit. You sucked. You played like a Vikings team. Yes, that's all true.
But SF played like a championship contender. They executed and dominated you, you pitiful non-tackling, non-covering Darrell Sharper imitator.
They whupped you.
You didn't deserve to win.
Everyone in the NFL has pro-level abilities. Even Tim Tebow. SF is good.
If the Packers are playing at their (Packers') best, the Packers are better than SF. If the Packers only playing at 80 % of their best, I'm not so sure.
And, based on that one game, I'm concerned about whether the Packers are ready/able to play at even 80% of their potential best.
But I'm still giving them a mulligan.
And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.
