Things to watch this weekend in the Atlantic Coast Conference:

Game of the week

No. 12 Georgia Tech (6-0, 3-0) at Duke (4-2, 3-0 ACC), Saturday, noon ET (ESPN)

Two conference unbeatens clash in a game that could have a significant impact on who plays in the ACC championship game in Charlotte.

The Yellow Jackets, who come in as a 1 1/2-point underdog despite not having lost this season, are led by QB Haynes King , an efficient passer and effective runner who averages 5.2 yards per carry. The Blue Devils are allowing 123.2 yards rushing per game on the ground, so Georgia Tech will be looking to exploit that weakness.

Duke QB Darian Mensah leads the ACC with 15 TD passes.
