Most QB's take years to prove themselves. Trust me, after watching ten plus years of crappy home town football with high hopes in the draft, high draft picks and FA signings being wasted at the position you begin to understand how hard it is to find the answer. I dislike the 49ers as much as any Hawk fan and don't want to see them be a thorn in the Hawks side but they should stay the course with Kap. Harbaugh moved all the chips to the center of the table when he went with Kap, no different than what most coaches do when they take over. If Kap fails so will Harbaugh. The coach will get kicked to the curb and 9 times out of 10 the GM will also. The QB is next. This hits the reset button on the franchise, rebuild project for 2 - 3 years minimum is what you can expect as a result.
Niner fans should be careful for what they wish for, they can be the Cards if they go down that road. JMHO. Kap does suck though.....
