I have to go back to the 4th quarter of Super Bowl XVII. Down 17-13 and facing a fourth-and-one on the Miami 43, Joe Theismann (yes, you young guys, he was once a player) handed off to John Riggins, who proceeded to take the handoff, break a tackle, and rumble all the way for a touchdown to give Washington its first lead of the game. The Redskins went on to win 27-17.
Of course, other images that come to mind are from Super Bowl XVIII: Jeff Bostic sailing a snap over the head of 'Skins punter Jeff Hayes, Jack Squirek's INT for a TD to end the first half (the last screen pass Gibbs called during his first stint in DC), and of course, Marcus Allen's 74-yard cut back run that dashed a young boy's dreams of back-to-back titles for his hometown team.
But as you can tell, I'm over it.
