They haven't stopped him the last two times they have played him here under Pete/Bradley. There isn't much that is going to change, since you have to prioritize and take away White and Jones as best as you can. The only savior from their first demolition of the Seahawks and the 61yd fg game of last year is that Burner Turner isn't as dynamic as he was a few years ago.
Remember, the Falcons was the team Pete felt the Seahawks needed to become for how they played. It may have changed with the emphasis on passing now but they were a handful to play under Pete's watch.
