Record: 1-0
Week 1 result: 34-31 OT win over New Orleans

One thing to know: Despite the result, Brian Hoyer did a lot to solidify his place as starting quarterback in the second half. Johnny Football will have to wait.
One thing to know: The Jags might have an actual defense on their hands. Nick Foles was completely stymied in the first half.

Thomas B. Shea/Getty Images
Record: 0-1
Week 1 result: 17-6 loss to Houston
One thing to know: A lot of quarterbacks are going to be destroyed by J.J. Watt and the Texans this year. But if RGIII struggles against Jacksonville in Week 2 ... yikes.
