After some careful thought, I think one game would have been more in-line with the penalty. Even though he didn’t mean it, PMB still did hit Calvert in the face with his stick.
It’s a lot like a car accident. You don’t mean to hit someone else, but you still have to deal with the repercussions.
I know PMB isn’t a dirty player and doesn’t want anyone to have to deal with a head injury since he knows how crappy they can be, but he still has to face the piper. A suspension was warranted, but like I said, I think one game would have fit the crime better. My guess is that Shanaban went with two games to drive the point home.
