They did a put in a disclaimer that there was a snap count minimum which excluded Tom Brady (injured for almost all of 2008) and Kurt Warner (retired after 2009). So maybe Rodgers's ranking comes with an asterisk because I would expect Brady to rank ahead of him.
It's an interesting list, topped with six obvious franchise quarterbacks, then Matt Schaub, who plays like a franchise quarterback even if he isn't as well known. Then it drops down to David Garrard at No. 8. It made me wonder what the Jaguars were thinking when they went with Blaine Gabbert in the April draft. Their league worst defense was what needed major help, not the quarterback position.
