>>The point is, it is the norm to beat the other team senseless.<<
The point is, these are high schoolers. If adults want to be morons, cool.
The point is, and Im not saying this to be rude, but you dont know football or how players think. High schoolers play that way too. And I do think it was unsportsmanlike, because if someone is conceding, the sportsmanlike thing to do is accept it. But I dont think it should be pushed into the legal realm.
