Alex Smith hasn't lost a football game since 10/14/2012.
Yeah he deserves all the credit for yesterday
He didn't eff it up, which isn't nothing (or maybe that's exactly what it is, but is better than a negative).
I honestly don't think there are too many other QBs in the league, if any, that would have this team undefeated right now. Not saying Alex Smith is the best QB, just that a lot of other QBs would be slinging the ball around and making enough mistakes for us to lose one.

Alex. A serviceable QB that we can move on from the second we get a better option.
Throw a couple 3rd round picks at QBs the next couple years and hope one develops. You draft a first round QB, usually you are reaching and definitely not taking the best available player. Then you put fan expectations on playing him regardless of if he is panning out and less than 50% pan out. Unless you have a top 2 or so pick, take a 3rd rounder when you can get better value and don't have the pressure to start him on the first weekend.
