The Dallas Cowboys are in London this Sunday, taking on the lowly Jacksonville Jaguars. Dallas is looking to bounce back after losing consecutive home games to Washington and Arizona. Tony Romo is expected to return after missing last week's game with a back injury, but if the Jaguars can't stop DeMarco Murray, it won't matter who plays quarterback.

Here are my keys to the game:

1. Jags Defense - Jacksonville ranks 24th in the NFL against the run, giving up an average of 123 yards per game. They should have their hands full with the NFL's leading rusher.

2. Blake Bortles - The rookie has thrown a league worst 13 interceptions, and he's been bothered by a wrist injury.

3. X-Factor - The Jags have lost eight of nine overall, and seven of those eight losses came by at least seven points.

Selection: This is a play on the Dallas Cowboys (8*)
