He's not singly to blame. The 7 goal game certainly hurt.
He's visibly slow off his line, indecisive and bad in distribution. You don't need an incredible athlete back there (it helps, look at Howard vs. Guzan right now), you don't always have to be well positioned (but if you are a poor athlete, the positioning helps, look at Pirlo) and you don't have to be a wonderful distributor of the ball (not everyone is Hugo Lloris). But you need to excel at something.
