Wisniewski committed 18 minor penalties in 75 games last year. If you break down the types of penalties he received it indicates that he does not have a tendancy to commit the same mistake over and over, which can be annoying to watch.
i personally love both of these incidents. the avery incident shows he doesnt take s*** from other teams. and apparently seabrook and him were really good friends when wizzy was in chicago. so it shows that wisniewski is all business on the ice, will defend his team (even if the other guy is a close friend), and sees himself as a lil bit of an enforcer.
and if you watch that second video a couple of times seabrook acts like his brain stem was just removed. the announcers noticed it, too.
