1 OUT OF ACTION
Clemson will be missing several players because of injuries. The biggest name is quarterback Deshaun Watson, who had surgery to repair a torn ACL after Clemson beat USC. Another key loss is tight end Stanton Seckinger, who suffered a knee injury against USC.
2 THE SERIES
Clemson and Oklahoma have played three times with the Sooners holding a 2-1 lead in a series that dates to 1963. The Tigers won the last meeting, beating Oklahoma 13-6 in the Jan. 2, 1989, Citrus Bowl in Orlando. The Sooners have thrown for just 198 yards in the three games combined.
3 MIXED EMOTIONS
Clemson defensive coordinator Brent Venables coached at Oklahoma for 13 years (1999-2011). In those 13 years, the Sooners had 13 winning seasons, went to 13 bowl games and had 10 seasons with at least 10 wins. Since Venables came to Clemson in 2012, the Tigers are 31-7.
4 TOPS IN DEFENSE
Clemson has the No. 1 total defense in the country, allowing 259.6 yards per game. That is the best total defense for a Clemson defense since 1990 when the Tigers allowed just 219.2 yards per game. That is the only other time Clemson has had the No. 1 ranked defense.
5 SACK MASTER
Can the Sooners block Vic Beasley? The Clemson defensive end leads the ACC in quarterback sacks with 11 and in total tackles for loss with 18.5. He ranked 10th in the nation in both categories. He was the ACC Defensive Player of the Week for his two sacks against USC.
