Why do people always fall for this shit?
There are so many cases where a team's starting QB goes out with injury, and the 2nd string QB comes in and has success, only to find out that they actually suck a few games down the line or the following season.
Alex Smith wasn't ruled out until yesterday (or today), so the Bears had to game plan for both him and Kaepernick. They probably spent more time game planning for Alex considering he didn't have a history of concussions, and players typically bounce back from them by the next game, especially with the added day of rest. So not only do you have a team who likely game planned mostly for Alex, but game planning against Kaepernick is going to be difficult considering there's little to no tape of him at the professional level.
Once he gets a few games under his belt, teams will be able to properly game plan against the guy. Once that happens, a defense is going to figure him out, effectively creating a blue print on how to defeat him that all future opponents will adhere too. And at that point, he'll begin to look like the inexperienced and mediocre 2nd string QB that he likely is.
It happens every fucking season, and yet people still fall for it.
