Matt M spoke with Steve Young. Young saying he is jealous about the Pistol formation. One interesting fact in the article:

"Matt Maiocco points out an incredible stat: Young never even took a snap out of the shotgun during his career. Not one. Kaepernick might be a descendent of Young in the history of mobile quarterbacks, but the game has changed dramatically since the last 49ers Super Bowl."

None? Wow.
