No. 21 Clemson hosts NC State in a key league matchup to headline the ACC weekly slate

Things to watch this week in the Atlantic Coast Conference:

Game of the week

N.C. State at No. 21 Clemson, Saturday, noon ET (ABC)

The Tigers regrouped from the season-opening blowout loss to Georgia with a romp against Appalachian State, then had an open week before hosting the Wolfpack. Clemson (1-1) was picked to finish second in the ACC race and N.C. State (2-1) was picked fourth, making this a key early matchup in the league title chase in the ACC opener for both teams.

N.C. State hasn't won at Clemson since 2002 with Philip Rivers at quarterback, but it has won two of the past three meetings. The Wolfpack quarterback situation is in flux, with freshman CJ Bailey set to start as Grayson McCall recovers from an unspecified injury.

The undercard

Georgia Tech at No. 19 Louisville, Saturday, 3:30 p.m. (ESPN2)

The Yellow Jackets (3-1, 1-1 ACC) started the season with a takedown of then-No. 10 and preseason ACC favorite Florida State in Ireland, which helped Georgia Tech crack the AP Top 25 for a week before falling at Syracuse.

The Cardinals (2-0, 0-0), who reached last year's ACC title game, have had a pair of lopsided wins against Austin Peay and Jacksonville State.

Jeff Brohm's Cardinals were picked to finish fifth in the league, while Brent Key's Yellow Jackets were picked to finish ninth.

Impact players

Omarion Hampton, North Carolina. The preseason Associated Press All-American is No. 6 nationally in average rushing (138.7 yards per game) and fourth in rushing yards (416). His 210-yard effort last week against North Carolina Central is the No. 4 output by a Bowl Subdivision player all season. UNC hosts James Madison on Saturday.

Teddye Buchanan, California. The transfer linebacker from UC Davis has made a quick impact with the Bears, racking up 31 tackles and 2.5 sacks through the first three games. Buchanan is one of 24 players in the Bowl Subdivision ranks averaging at least 10 tackles (10.3) entering this weekend's trip to Florida State.
