Here's what we learned in the ACC in Week 6:

1. FSU should be the unquestioned No. 1. Florida State did what it was supposed to do and beat Wake Forest 43-3 on Saturday. The Seminoles are now 5-0, and there should be no doubt they are No. 1 after No. 2 Oregon, No. 3 Alabama and No. 4 Oklahoma lost. Yet there are those who might not see the Seminoles as No. 1, not after Auburn, Mississippi State and Ole Miss turned in wins over ranked SEC opponents. The voters should be reminded Florida State has won 21 games in a row. It beat an improving Oklahoma State team, ranked No. 21 and rising, to open the season; it beat Clemson with a backup quarterback; and it outscored NC State 49-17 after a disastrous first quarter this past week. Not every win has been impressive, but Florida State has found ways to beat one ranked team, beat another with a backup and overcome a 24-7 deficit. Clemson, by the way, will be ranked before too long, so that win will only look better and better. The Tigers are a far different team with Deshaun Watson under center. Of course, the rankings don't really matter right now. If Florida State beats Syracuse and Notre Dame, it will be very happy with where it stands when the first College Football Playoff committee rankings are released Oct. 28.

2. Virginia and Georgia Tech are the Coastal front-runners. Believe it! The two teams in the Coastal with the most questions headed into the season have gotten off to 2-0 starts in league play and sit atop the division. For now. While there always is a caveat in the Coastal, both teams deserve to be there. Georgia Tech ended long losing streaks to both Virginia Tech and Miami. Its 28-17 win over the Canes on Saturday night was as thorough an offensive domination as you can get. The Jackets rolled up 311 yards rushing and 21 first downs, converted 9-of-14 third-down attempts and held the ball for 40 minutes. They also came up with two turnovers to kill Miami drives. The Canes' defense reverted to form and looked lost for most of the night against a team that has the most predictable offense in the ACC. Virginia, meanwhile, held on to beat Pitt 24-19 behind a career game from Kevin Parks, who had 169 yards and a touchdown. Considering how the Panthers outplayed the Hoos in the second half, this is a big win for Virginia. Maybe a season ago, the result would've been different. No, the officiating was not very good in the game, but Virginia found a way to win. The Nov. 1 matchup between Georgia Tech and Virginia in Atlanta is looking pretty big right about now.

3. The two-QB system isn’t working for UNC. Mitch Trubisky was 1-of-4 for 11 yards and threw a disastrous pick-six during his limited time on the field in a 34-17 loss to Virginia Tech, and once again Tar Heels fans are wondering why Larry Fedora insists on the merry-go-round at QB. Marquise Williams has said the right things, but the off-and-on approach is clearly affecting him, while Trubisky isn’t getting nearly enough reps to make real progress. With UNC’s Coastal hopes on life support, it’s time for Fedora to pick his QB -- either to try to win now or to prep for the future. It is not as if the schedule gives them any breaks, either. North Carolina is at Notre Dame next weekend, with games against Georgia Tech, at Virginia and at Miami to follow.

4. NC State isn’t ready to contend: Clemson could do what Florida State couldn’t: get consistent pressure off the edge on NC State in a 41-0 blowout. The Tigers’ pass rush utterly smothered Jacoby Brissett, whose problems with fumbles under pressure continue to cost the Wolfpack. Meanwhile, NC State’s porous defense looked bad again, and while it’s clear Dave Doeren’s crew is better than it was a year ago, the ACC losing streak is now at 10 games, and there’s no debate who is the second best team in the Atlantic Division. Watson finished with 329 all-purpose yards in another solid performance, which left many to wonder what would have happened had he been the starter when the season began.

5. Louisville can win with defense: The Cardinals haven’t allowed more than 300 yards in a game yet this season and notched another outstanding effort in a 28-6 win over Syracuse on Friday night. Its 12 interceptions through six games were more than six ACC teams had all of the past season. Gerod Holliman has seven picks in six games -- something no one had done since FAU’s Tavious Polo in 2007. The defensive front has racked up 21 sacks already, and no opponent has averaged even 3 yards per rush. Yes, Louisville is having some offensive struggles in the early going, but it might not matter if Todd Grantham’s unit keeps playing this well.
