Three games to watch

Oklahoma State at Texas

3:30 p.m. (ABC-36)

Rankings, records: No. 7 Oklahoma State 7-0, 3-0; No. 1 Texas 7-0, 3-0

What to watch: Texas junior quarterback Colt McCoy established himself as the mid-season favorite for the Heisman Trophy with a 29-for-32 passing performance last week in a 56-31 win over Missouri. He is completing 81 percent of his passes and after seven games still ranks as the Longhorns' top rusher with 371 yards and six touchdowns.

Georgia at Louisiana State

3:30 p.m. (CBS-27)

Rankings, records: No. 9 Georgia 6-1, 3-1; No. 11 LSU 5-1, 3-1

What to watch: It's the same old high stakes between the two teams with the most wins in the SEC during the past five years. Both squads still harbor aspirations of playing for a national title in January, despite having lost one game apiece. A second loss, however, could make it tough to win their respective divisions in the SEC, never mind the BCS title.

Penn State at Ohio State

8 p.m. (ABC-36)

Rankings, records: No. 3 Penn State 8-0, 4-0; No. 10 Ohio State 7-1, 4-0

What to watch: Ohio State freshman quarterback Terrelle Pryor, 5-0 as a starter, will be the central figure in a game likely to determine the Big Ten champion and its BCS representative. Penn State was one of Pryor's final four college choices, but the Jeannette, Pa., native chose Ohio State instead. Penn State is 0-7 at Ohio State since joining the Big Ten.
