Another small tidbit, Chad Pennington's career completion % of 66 is higher than Manning, Brady, Brees, and River's (didn't even bother looking at the rest of the elite QB's)
Now, take that for what it's worth. I am, by NO MEANS, saying he is BETTER than any of those QB's but what I am saying is, when giving the opportunity to drop back and pass, he makes the most of it and that is exactly what this offense has missed for a while.
There is nothing wrong with a "game manager" if in fact, you are very good at managing the game. You are not a "game manager" by default because you are not a "play maker", you have to earn that title by being successful at it and Chad has definitely earned that title.
