I went to a meaningless pre-season game (aren't they all) between the San Francisco 49ers and Dallas, when Steve Young was running the team in place of Joe Montana. Young has the Niners down to the Dallas 10 and lines them up wide right, then throws a little flare to the left. Dallas DB reads it all the way, intercepts in stride and takes off with 90 yards of wide open space for the touchdown.
Except here comes Steve Young from the far side of the field, finding the angle and sprinting like mad. The crowd goes wild. He's actually catching up to the guy....and dragging him down from behind a good 15 yards from the end zone.
I don't even remember if Dallas scored. And like I said, the whole game was meaningless. But it remains one of the most impressive mental and physical displays I've ever seen a quarterback put on.
For what it's worth, Ganz is taller than Steve Young.
