I don't remember Hebert doing that, but I wouldn't have put it past him. I do, however, remember Steve Walsh did it in San Fran in 1992. Best part of that game was SF had 4th and goal from the 1 or 2. They called timeout. During the timeout, the Saints D was emphatically signalling to Bill Walsh, et al, to go for it. I'm pretty sure they did, and we held. Too bad we lost the game.
