Take that, Colts: 49ers extend their lead

Posted by ESPN.com's Mike Sando

Alex Smith was outstanding for the 49ers as they ran their 2-minute offense toward Vernon Davis' seventh touchdown reception of the season and a 14-6 lead over the Colts.

That was the type of drive I was talking about when assessing what the 49ers would have to do to win this game.

This should be a fun second half to watch.

We know Peyton Manning will likely warm up at some point, even if the 49ers keep playing well on defense. Smith and the 49ers have shown they can also open up the offense, a very good sign for San Francisco and an unexpected one given what we knew about the 49ers' offensive line.
