One of the very few to reach the 1000 game mark in their career, Roberto Luongo is one of the most revered goalies in recent history. Although he played most of his career with the Florida Panthers, Luongo was a high-profile figure in his time with the Vancouver Canucks, so much so, that fans still send him hate mail to this day.
It's certainly a hilarious piece of hate mail to receive from a fan, especially about a subject so trivial like suggesting support for a special jersey. Luongo became a polarizing figure in Vancouver because of his contract, but in reality, he was a great goaltender for them.
It's no surprise that Luongo would've shared this type of mail received by a fan, as he's always been a fun guy and a good sport about this kind of thing. For hockey fans, it's a hilarious example of a fan taking things way too far, and the player making an example of him.
