Above link has a great story on what CK can do:

SAN FRANCISCO -- Now we know Colin Kaepernick can do some amazing things in the NFL.

Well, at least one thing.

But what a thing that was Friday night -- a faked handoff out of the shotgun, an Olympic sprint down the right sideline and an easy discarding of Minnesota Vikings cornerback Chris Cook 60 yards downfield.

The result: Kaepernick's blistering 78-yard touchdown run in the second quarter on his second snap in the 49ers' 17-6 exhibition victory over Minnesota at Candlestick Park.

"Our offensive line did a great job of blocking the box, our receiver blocked the corner, our tight end got up to the safety, which left me with a lot of green grass," Kaepernick said.

It was a Steve Young-level run. If Tim Tebow had done this, there would be songs sung on ESPN about it.

Sure, it's only the exhibition season. It doesn't count. But, still, that run was a breathtaking reminder of what's possible with Kaepernick, a second-round pick last year and the 49ers' incumbent backup quarterback.

Another thing we know: If coach Jim Harbaugh ever wants to turn the 49ers into the footloose, read option Oregon Ducks, he has the quarterback to do it.

Of course, Harbaugh is never going to abandon his devotion to power-offense philosophies, fullbacks and tight ends, and to lining up and shoving the defense as far backward as possible without New Age trickery.

Colin is now solidly the 49ers' #2 QB.

The best part of CK is that he can run in one direction and then throw in the other. Very few QBs can do this accurately... Combine this with his speed and you've got a monster waiting in the wings.

Hopefully the 49ers actually let him off the bench from time to time this year. He's ready to play!

He's not a typical Harbaugh quarterback, which makes him doubly exciting.
