I really don't know why people hate this guy so much. His job is to protect young guns and star players, period. SmackIntyre is getting paid good money to protect not to hit or score goals is it really so hard to accept?
If the Pens are smart they are going to recall him soon, which would give them BigMac, Engelland and Asham 3 players able to protect Crosby.
Problem with Mac is that he's just too bad at the sport. It's easy to duck a guy who plays 2 minutes per game and tough as a coach to put him in any more than that because he's an outrageous liability in terms of his ability to skate a regular shift. He'd wreck a thornton or prust bad, but those guys have a future in the sport and Mac doesn't precisely because they CAN play a little.
