Video: Key points on 49ers' QB situation

San Francisco 49ers coach Jim Harbaugh brought no clarity to the team's quarterback situation in public comments Wednesday.

I used our latest "Blogger Blitz" video to take a bigger-picture view of the situation.

Alex Smith's relatively modest contract allows the 49ers to more seriously consider moving Colin Kaepernick into the starting lineup. For all we know, Smith could remain the starter and lead the 49ers to a Super Bowl. I believe this team can win it all with Smith behind center. I can also see reasons for giving Kaepernick an opportunity to build upon his impressive performance against Chicago on Monday night.

Smith still must gain medical clearance after suffering a concussion against St. Louis in Week 10. Until that happens, there's no decision to be made. But there are a lot of things to consider.

Note: I said in the video that Smith signed a deal ranked 18th among starting quarterbacks. It might have been 20th.
