You guys crack me up jumping on and off bandwagons before they even go thru a full season. Tolzien could very well be like Brady, nothing to look at but having that hidden something. JH harbaugh did want to sign him as an UDFA, but he chose the Chargers. Of course Tolzien has an advantage just like Stanzi had an advantage they both played in a pro style offense. I was one of those that would not have minded if the niners spent a seventh rounder on one of those two-using the shot gun approach of hitting on the niners future QB. In fact Tolzien's Wisconsin Badgers ran a form of WCO from what I read and one of his coaches is the brother of current niners QB coach. So I expect Tolzein to be farther along. Question is how much more ceiling room does he have.
Kaeps ceiling is very high, but will he reach it is dependent what you can't see between his head. He certainly has the physical tools and confidence. Not saying he is Brett Farve, but if you remember Farve coming out in his first year at Atlanta was similar, but Holmgren saw his potential and molded him. Same with Steve Young, raw talent. Still has to be molded, rare are the Dan Marinos, Ben Rothlesberger who come in day one and flourish.
Give them both time and we will find out at years end or after when the shot gun has been fired, which one hits.
