There’s a difference between a bump and taking someone’s fender off.
Not to me. Both were monkeying around during the caution. If you approve of ruff stuff then both are fine. If you do not then neither are fine. Then the 88 car piled in. Kind of like when the corner back pokes a wide receiver in the eye. then the wide receiver punches the CB. Typically the WR gets the penalty and the line backer that sees the WR hit the CB takes off his helmet and gets ejected. If the 88 would have raced the 20 instead of bumping him during the caution he would still have his fender.
