Aww c'mon now. That's not a very fair statement. His rookie year playoffs (4.41 GAA, .835%) has made his playoff stats look worse than they are.
His year by year playoff stats:
06-07 - 2.07 GAA, .924%
07-08 - 2.57 GAA, .909%
08-09 - 3.00 GAA, .908%
10-11 - 2.25 GAA, .917%
Not his fault the Rangers couldn't score goals those years.
