That goal wasn't Klein's fault - that was Hamhuis' fault. Hammer didn't tie up his man.
Wait, what? Klein was off on the boards, while 2 Wings were in front. You want Hamhuis to take out 2 while Klein sits and does nothing? I'm pretty sure it wasn't Hammer's job to take out two. Call it all you want, but there should not be 2 Wings in front, and 1 Pred.
