ACC internal affairs

Posted by ESPN.com's Heather Dinich

1. Clemson: Quarterback Cullen Harper said Tuesday he's dealing with a sprained AC joint in his throwing shoulder, an injury he suffered in the season opener against Alabama. Clemson's injuries and inexperience on the offensive line are obviously part of the problem, but a bit of tension between Harper and coach Tommy Bowden won't help things. Bowden said Harper needs to play better after going 14-of-18 passing for 192 yards and a touchdown against the Citadel. Harper said "come to me and say it."

2. Florida State: Finding the right combination on the offensive line is the main priority right now before heading into ACC play against Wake Forest. Offensive line coach Rick Trickett publicly called out left tackle Zebrie Sanders, saying "I didn't think he played very well." Trickett was impressed with Andrew Datko and right guard David Spurlock, "but the other guys, those two freshmen, we've got a little ways to go there." Trickett still hasn't made much use of junior college transfer Joe Tonga at right tackle.

3. Georgia Tech: Most of the focus has been on the offense, but the Yellow Jackets' secondary has quietly picked off four passes in two games. It's quite an improvement considering they only had five interceptions all of 2007. Part of that is a result of the tremendous pressure Georgia Tech is bringing up front, but it's also showed a fearlessness from younger players. True freshman safety Cooper Taylor had six tackles against Boston College and cornerback Rashaad Reid made his first career interception.

4. NC State: The Wolfpack is looking for offensive playmakers to replace injured starters, as they're down to their third-string tight end, leading rusher Jamelle Eugene is out and top wide receiver Donald Bowens is out. Keep an eye on T.J. Graham, a blazing wide receiver and kickoff man who is the league's top freshman in all-purpose yards. And tight end George Bryan made the most of his promotion, as he had five catches for 41 yards and a touchdown last week. Quarterback Russell Wilson, who was out last week with a severe concussion, will make his comeback in Death Valley.

5. Virginia Tech: Despite quarterback Sean Glennon being outspoken about the staff's decision to use Tyrod Taylor last weekend, coach Frank Beamer said that wasn't the reason he put a muzzle on the quarterbacks this week. "I just think we spend all our time talking about quarterbacks and I want to talk about Georgia Tech." Beamer is looking for his team to block better and more consistently and wants his offensive line to continue to improve. The most progress came in the kicking game, and the tackling improved from Week 1 to Week 2.
