They are one of the most mean-spirited characters in South Park.
None of the Red Wings players care at all about Nelson's cancer and the pee-wee team getting destroyed in bloodshed.
The injuries the pee-wee players get during the match are too sickening and ultra-realistic, even by South Park standards. This includes scenes where a puck hits one boy bloodying his face and Ike getting repeatedly punched by a Red Wings player.
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 overdramatization 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.
Thankfully, they never appeared again afther Stanley's Cup.
They are better in real life, and aren't even malicious at all.
