Let's take a look at the box score from this year's Atl-GB game.
M. Ryan 16-26, 61.7 comp%, 2 TD, 1 INT, 94.1 QB Rating
A. Rodgers 25-37, 67.6 comp%, 3 TD, 1 INT, 109.4 QB Rating
I guess you can't lose with either. Seriously though, I would take Rodgers as my QB over Ryan just because he's had more experience in the NFL. Nothing against Ryan, he's been amazing for a rookie that inherited that team.
