The 2013 quarterback class might lack a surefire superstar like Andrew Luck, but, in my opinion, it could be among the deepest classes ever. The level of refinement at the position just seems to grow every year. And, by next April, teams way down the board could still be looking at great options. There's Matt Barkley, Logan Thomas, Tyler Wilson and Geno Smith. There's Tyler Bray, Mike Glennon, E.J. Manuel and Ryan Nassib. Even lesser-known guys such as Zach Mettenberger and Casey Pachall could emerge. Perhaps Aaron Murray or Tajh Boyd will be in the picture.
