probably because klein makes bad plays more often.
Lately, Shea is committing as many boneheaded plays as anyone in the league. Every time, he gets a pass. When he and Suter blew several plays and left the entire team out to dry ... nothing. When he turns the puck over in and it leads to a goal ... nothing.
The consistency of Colin Campbell is demonstrated here yet again. If Klein screws up, call him on it. If Shea screws up, call him on it as well.
