Week 1: Upset watch

It happens when you least expect it.

Just ask Virginia Tech.

Can the ACC get through Week 1 without an embarrassing loss? Will JMU strike again?

Here are the top three games on upset watch for Week 1 in the ACC:

1. William & Mary at Virginia: The last time these teams met, in 2009, William & Mary won, 26-14. UVA was 4-8 last year. William & Mary was 8-4. The Tribe is led by former UNC backup quarterback Michael Paulus, who played in six games last season. Virginia is introducing rookie quarterback Michael Rocco. The Tribe ranked seventh in the FCS in passing offense last year and No. 19 in scoring offense at 48 points per game. UVA's offense was much improved under Bill Lazor and averaged 38 points per game.

2. Appalachian State at Virginia Tech: This is the fourth straight season that the Hokies have played a past FCS national champion, but these programs haven't met since 1982. App State quarterback DeAndre Presley is one of four players in FCS history to pass for 2,000 or more yards and rush for 1,000 or more in the same season.

3. James Madison at North Carolina: Mickey Matthews is entering his 12th season at JMU, and interim head coach Everett Withers will be coaching his first game as a head coach. Despite its upset of Virginia Tech last season, JMU didn't exactly thrive in the CAA, finishing with a 3-5 league record and 6-5 overall. The offense was one of the worst in the FCS, and shouldn't present too many problems for the UNC defense. The JMU defense, though, was one of the best in the FCS.
