Unsportsmanlike conduct? The definition of unsportsmanlike is “not fair, respectful, and polite toward other players when participating in a sport.” This is a game predicated on running violently at full speed into other people. The whole sport is rather unsportsmanlike. It’s a dumb name for a penalty in a sport like football.
Unnecessary roughness is another one that’s dumb. We’ll take some amount of roughness. But you know what, that roughness was just unnecessary.
