Kaepernick has shown that he can throw the football very well, particularly on intermediate throws. He might not have Flacco's incredible touch in the vertical game, but for a guy with just nine NFL starts under his belt, he's shown ridiculous upside. At this point with Flacco, we know what we're getting. He's a good quarterback who doesn't complete a high percentage of his passes but can seriously hurt teams with the deep ball and plays relatively well in the postseason. The sky might be the limit with Kaepernick, even though the jury is still out at this point. Nonetheless, if you're starting from scratch, it's all about upside.
