It's easy to forget that Colin Kaepernick is an NFL pup.The San Francisco 49ers quarterback's sublime performance against the Green Bay Packers on Sunday was just his 11th career start. I know, I know, it certainly doesn't seem that Kaepernick doesn't yet have a full season as an NFL starter under his belt.He already owns an NFL quarterback single-game rushing record and was a play away from winning a Super Bowl.Still, the 25-year-old is still learning.
