QuoteSea, the life in a few words
Don Herold quote
Well, we emphasize that you call it when it occurs at the point of attack and if it has a bearing on the play. And even then, it's up to the official to use his discretion as to whether it's a fender-bender or a train wreck. If you arm-clamp or take down the defender, that's what we call a train wreck.
