Turner is more important to the Falcons than Ryan.
If he wants to make the argument that the MVP is the player that is most valuable to his team, then the winner should be Tony Romo hands down. Or, more techincally, Tom Brady---his team is vastly different without him in there.
If he wants to make the argument that the MVP is the most valuable player to the league as far as performance and bring fame to the league, then Matt Ryan doesn't sniff the top 10 on that list.
The only way the MVP is Matt Ryan is if you define MVP as "most valuable player to play QB for the Falcons".
