The ACC entered Week 6 with two unbeaten teams and it escaped Week 6 with two unbeaten teams, as Clemson and Florida State remain atop the league Power Rankings. There is a new No. 3 and the same No. 14. Everything in-between? Very, very fluid -- a theme we will likely be repeating in the ACC throughout this season.

1. Clemson Tigers (5-0, 2-0). Clemson built off a big win last week against Notre Dame and took care of business against Georgia Tech, jumping out to an early lead and never giving the Yellow Jackets much of a chance. It is early, and FSU is always dangerous, but the Tigers certainly look like they’re in a class of their own through the first five games of the season.

2. Florida State Seminoles (5-0, 3-0). FSU made it six in a row against in-state rival Miami, as the Noles extended their ACC winning streak to 27 games. Perhaps a visit from Louisville could be tricky, but the Noles are only getting better, especially as quarterback Everett Golson continues to improve.

3. Duke Blue Devils (5-1, 2-0). Duke did exactly what it was supposed to do at Army, and its defense again looked dominant, as the Blue Devils are now surrendering just 9.3 points per game. Thomas Sirk was much sharper as well, and if he can build off Saturday’s performance, you have to like Duke’s chances to be the Coastal front-runners.

4. North Carolina Tar Heels (4-1, 1-0). UNC had a bye after a comeback win at Georgia Tech last week, with rival Duke passing the Heels on Saturday. No matter, as UNC has the chance to make it five in a row Saturday when it hosts this year’s crossover Atlantic opponent, Wake Forest.

5. Pitt Panthers (4-1, 2-0). Pitt notched its 700th win in program history Saturday, and even though its victory over Virginia was uneven -- in addition to not being decided until the game’s final possession -- Pat Narduzzi has to like the way his defense is performing through two games in ACC play.

T-6. Louisville Cardinals (2-3, 1-1). Louisville had a bye Saturday after notching its first two wins of the season. If the Cards can make it three in a row -- Saturday at FSU -- then things start to get very interesting in the Atlantic Division.

T-6. Miami Hurricanes (3-2, 0-1). The good news for the Canes is that the loss at FSU counts as only one in the standings, and it was their first ACC game. The bad news? Well ... it could be that there are seven ACC games left. Miami is 2-6 the last two years in the games after losing to its archrival, and a quick rebound will be necessary if the Canes hope to salvage their season.

8. Virginia Tech Hokies (3-3, 1-1). The Hokies moved up five spots after an impressive Friday night home performance against NC State. Brenden Motley and the offensive line looked much improved, and Virginia Tech has to feel exponentially better about itself moving forward than it did at this time last week. A trip to Miami will be very interesting, to say the least.

9. Wake Forest Demon Deacons (3-3, 1-2). The Deacs jumped three spots by notching their first road ACC win of the Dave Clawson era. Yes, the victory at Boston College was beyond ugly, but that defense made a couple of very impressive stops late to escape victorious. The Deacs have already matched last year’s win total.

10. Boston College Eagles (3-3, 0-3). Speaking of BC ... boy, does that offense need a jolt. The Eagles are averaging a paltry 5.25 points per game against FBS competition. They now must win four of their final six games to make a bowl, since two of their three wins are against FCS opponents. That defense is ridiculously good, though, giving up just more than seven points per game this season.

11. Syracuse Orange (3-2, 1-0). Just when you think there is a surprise team ready to emerge out of nowhere in the ACC, Syracuse goes ahead and loses at USF. The Orange’s first road game of the season proved to be a much tougher task than anticipated, and a trip to Virginia next week ought to play a large role in the Orange’s potential bowl hopes.

12. Georgia Tech Yellow Jackets (2-4, 0-3). There is no team that has disappointed more in the ACC. Heck, there might not be a more disappointing team in the country. The preseason Coastal favorites dropped their fourth straight contest, at Clemson, and an offense that looked unstoppable last season looks lost halfway through the 2015 campaign.

13. NC State Wolfpack (4-2, 0-2). The Wolfpack offense continued to struggle Friday at Virginia Tech, a week after Louisville stopped it in its tracks. Big numbers through four lightweight nonconference games have disappeared, and NC State will have a bye week now to try to get back on track.

14. Virginia Cavaliers (1-4, 0-1). UVA looked much better at Pitt than it did two weeks ago against Boise State, but it still wasn’t enough. A visit from Syracuse might offer a reprieve for a Hoos team that had an unforgiving slate to open the season, but this team still has a long way to go, needing to finish 5-2 just to make a bowl game.
