All this week, we’re taking a fresh look, position by position, at how ACC team stack up — from the best of the conference to the units that might surprise to the positions that will prove to be an Achilles heel for some teams’ 2017’s title hopes.

Best overall: Clemson Tigers

The unit needed some time to grow last year, but by season’s end, Clemson’s front had become a force. So while there are ample questions about who’ll be starting at quarterback or carrying the load at running back, the guys in the trenches look stout. Mitch Hyatt is among the best tackles in the country. Sean Pollard and John Simpson got ample work as true freshmen, and they could be stars in 2017. Tyrone Crowder and Taylor Hearn have plenty of experience under their belts, too, and the depth goes well beyond that. The loss of Deshaun Watson won’t be easily overcome, but the foundation of Clemson’s offense should be excellent once again in 2017.

Runner-up: Georgia Tech Yellow Jackets

Sure, longtime starter Freddie Burden moves on. But the rest of the group took such a big step forward last season, that it’s easy to see the unit not missing a beat in 2017. Parker Braun came into his own as a freshman, Trey Klock and Will Bryan made strides as sophomores, and Paul Johnson added more young talent this recruiting cycle with Michael Minihan and Zach Quinney.

Potential sleeper: Florida State Seminoles

Last year’s unit was not great. In fact, when it came to pass blocking, it was downright bad at times, and it’s tough to gauge the run blocking when Dalvin Cook can make anyone look good. But there were signs that this unit could take a big step forward. For one, younger players like Landon Dickerson got experience. Developing linemen like Alec Eberle ad Brock Ruble got better. And a host of depth toiled in the background and should be ready to contribute in 2017. Add to that a unit that showed more push up front as the year progressed and the fact that quarterback Deondre Francois should have a bit more pocket awareness in Year 2 as the starter, and there’s a strong chance last year’s weak link on offense could turn into a strength this season.

Achilles’ heel: Louisville Cardinals

OK, we’re not breaking any big news here. Louisville’s line wasn’t just bad last year, it was laughably bad (unless, of course, you’re a Louisville fan, in which case, there was nothing to laugh about). But Bobby Petrino brought in a new offensive line coach in Mike Summers, along with a host of talented youngsters in this year’s signing class. If the unit is even league average in 2017, Lamar Jackson will make this a potent offense. But if the new approach and young kids can’t step up quickly, it could be another year of Jackson running for his life and another season of missed opportunities for the Cardinals.
