I watched YAZ play for years and I never saw him smile during a game. Of course, YAZ wasn't being paid millions of dollars. That might have made him smile.
I believe you're way off base on that. This team had the most player time missed due to injuries in the NHL and still finished 2nd in total points. The 2 games the BRUINS lost to the Blues, the BRUINS were only playing with 5 defensemen due to injuries.
I heard he may have a broken jaw. Don't expect to see him in the remainder of the series. Bruins are so short on defensemen they may have to suit up Bobby Orr.
