Pretty sure the real stupidity on the PK was Hernandez for standing over the ball at the edge of our box. Pass the damn ball!!!
To me, that's the same reasoning that leads me to find Saunders most at fault for the first. Other people were at fault, sure. First, Pirlo was probably fouled in the first place, but he gives the ball away. Then, Mena got beat covering for Matarrita, but at least he showed Kaka to an angle where it was very difficult for him to score, and the other defenders recovered nicely to block any cutbacks. Then Saunders gift wraps the goal by more or less Bucknering a soft shot.
His consistent repeated mistakes are really frustrating to many of us. Throughout the game, yet again, he was diving for no reason. He also completely flapped at air on an extremely dangerous cross, and we were lucky to get away with it (I think it was a deadball kick of some sort).
