The pick of Kaepernick was interesting as he was a great runner in college and piled up yardage as a passer. Because of the league he was in (think Jimmer) there were obvious questions about whether a guy who wasn't even recruited out of high school would be able to throw and have the judgment to be an NFL quarterback. Well, then, here we are with a guy who not only can throw but seems to have amazing judgment.
Do any rookies play at all? I don't think so.
Then there is Harbaugh! Who else would turn linemen into blocking backs?
