Crosby did some crazy shit in his day. I wish I could find the clip, but sadly after searching for a while I couldn't find it. However I clearly remember in a regular season game the year after the Red Wings beat the Penguins for the cup. Crosby lost it after they lost to the wings again in regular season and started cross checking Zetterberg in the head as the time expired. I thought at the time it would be a suspension, or at least a fine, but nothing came out of it. Zetterberg didn't miss any time, so I'm sure that was a factor.
