It's to the Kings and Staples everlasting shame that he wasn't booed to inaudibility.
The thing is, most people there wouldn't have even know why they were booing. Other than simply being sheep. Booing him is wasting energy on what was really going on. If you let him bug you THAT much moments after your team wins the Stanley ****ing Cup.....you have issues.
I remember discussing with my friends that I did not want to boo him because I didn't want a negative vibe to ruin the celebratory atmosphere. I now regret my decision. I hope that, if he awards the Cup again, the fans in attendance boo so loudly that it is impossible to hear anything he says.
