He consistently trips or punches opposing players, and is just a nuisance on the ice.
Although he has been called out for his ridiculous behaviour before, it now looks like things are getting more serious.
St. Louis Blues head coach Craig Berube addressed Binnington's behaviour in an interview following the teams' game against Pittsburgh. In this game, Binnington tripped Jason Zucker and sent him into the boards.
The antics just have to stop. Just play goalie. Stop the puck. Enough's enough.
If Binnington doesn't manage his anger, this situation could get even worse. It will be interesting to see if Berube's words have any effect.
