In NFL circles, we often find people comparing one quarterback to another from the same draft class. From Andrew Luck and Robert Griffin III in 2012 to Jameis Winston and Marcus Mariota in 2015, it happens a lot.
That being said, there are certain drafts where that doesn't happen for one reason or another. The 2005 draft is one of them.
It all boils down to the disparity in the career timelines of Alex Smith and Aaron Rodgers, the first two quarterbacks selected 12 years ago.
