Maybe there were bad calls that hurt the Niners and maybe there weren’t. It doesn’t matter. You play the game and you don’t bellyache.

You keep playing. If you are using bad calls as an excuse for the Super Bowl loss and if Jim Harbaugh is doing the same, please man up — or woman up or person up. We are PC on this blog.
