The Misshapen Steed
It's disrespectful to the other team to attempt to put the puck in the net on a whistle.
Disrespectful and unsportsmanlike are synonymous. What about it is disrespectful?
The fact that there was no hockey benefit to it and it was only done to antagonize the other team. It's childish.
Antagonizing the other team is an extremely common and, more often than not, a non-penalized occurrence in the NHL. The "hockey benefit", however, was pretty obvious; it lead to the power play being negated.
