But, the article doesn't discuss how difficult it is to actually draft a good QB. Just because a guy is a 1st round pick or is handed a starting job, it doesn't make him a good QB.
Rex Grossman, Kyle Boller, Byron Leftwich, Joey Harrington, Patrick Ramsey, Tim Couch, Akili Smith, Cade McNown, Ryan Leaf, Jim Druckenmiller, Heath Shuler, Dan McGwire, Todd Marinovich, and Rick Mirer were all 1st round picks. Would you take any of them over Tom Brady, who was a 6th round pick? Obviously, you need good Qb play to win. But, taking a QB in the first round is no guarantee that you are going to get it.
