They are some of the most mean-spirited characters in South Park's history, so much that their bad actions can even give early Shelly Marsh's abusive behavior a run for its money. They also behaved nothing like their real-life counterparts.
None of the Red Wings players care at all about Nelson's cancer (just like Gavin Throttle); and the pee-wee team getting destroyed in bloodshed.
The injuries they give the pee-wee players during the match are too sickening and ultra-realistic, even by South Park standards. This includes scenes where one Red Wings player hits one boy with a puck, bloodying his face and another Red Wings player repeatedly punching Ike.
In a final match, the pee-wee team gets assaulted, tortured, beaten up, and bullied by the Detroit Red Wings. They not only get away with attacking children but also for some reason win a cup without any sportsmanship.
For their lack of sportsmanship, they are a terrible over-dramatization of arrogant and mighty sports teams. In a real NHL game (or ANY professional sports team nonetheless), an adult league would not be allowed to face off against a peewee kids' league!
The portrayal of the team is a prime example of a Karma Houdini.
They are better in real life, and aren't even malicious at all.
