10. Matt Ryan, Atlanta Falcons
For anyone who thinks that offensive coordinators don’t really make a difference in how a quarterback performs, take a good look at what happened to Matt Ryan. He’s still a really good quarterback, but he isn’t putting up anywhere near the same production now that Kyle Shanahan left Atlanta to take the head coaching position in San Francisco. Needless to say, Steve Sarkisian is not Kyle Shanahan. After averaging 309 yards passing per game last year, Ryan is averaging 256 yards per game, and is on pace to throw for 24 touchdown passes this year, compared to the 38 touchdowns he threw last year.
