And there are no "what ifs" surrounding Drew Henson, Philip Rivers, and JP Losman?
AJ Feeley is a strong armed young quarterback with limited experience, but in the experience he has, he has posted a career 79.3 QB rating, thrown 8 TDs to 6 INTs, completed 57.1% of his passes, averaged 6.87 yards per pass attempt, and didn't crumble under the pressure of being thrown into the fire on a team competing for a playoff spot. The last thing on that list should let you known about what type of mentality this QB has, and that should not be understated.
This guy is better right now than Matt Hasselbeck was when he was traded in 2001.
