I remember a game between the Redskins and Cowboys, where Tony Dorsett broke into the open on a run and thought he was headed for the end zone. But Darrell Green caught him from behind.
Dorsett had a surprised look on his face when he got up off the ground.
Now if it sounds like I'm a Dorsett/Cowboys homer/apologist it's because I am, but still, these things have to be borne in mind when thinking about that play. Having said that, Green was scary-fast.
A dream race betwixt he, Bob Hayes, Bo Jackson, Alexander Wright, Hershel Walker, OJ, Joey Galloway, and Deion Sanders would have been a mega event.
