If Colin Kaepernick leads the 49ers past the Ravens in tonight's Super Bowl, quarterback-starved coaches might be tempted to start looking for his clone.

Just one problem: The chase is as difficult away from the field as it is on it. Kaepernick's deer-like speed has given the Niners a tremendous advantage this season, most notably during their playoff victory against the Packers when he rushed for 181 yards and two touchdowns without being touched. His ability to translate his athleticism from college to the NFL is rare, but that's what makes him special.

The read option and pistol formation are great, but this isn't the first time they've been utilized in the pros. Just remember the Wildcat, which was successful for a season or two but has since nearly disappeared.

That's not to take away from Kaepernick, or Redskins quarterback Robert Griffin III, or Seahawks quarterback Russell Wilson or even new Eagles coach Chip Kelly, who will use some hybrid of his successful system from Oregon. This movement will continue to succeed as long as the teams find the right players.
