Week 7 is shaping up as a big one in college football, with Oklahoma-Texas and USC-Notre Dame leading the way. As for the NFL implications, interior matchups in those games and two others will be watched closely by pro scouts.

Among the four premier matchups between pro offensive tackle and defensive end/outside linebacker prospects, and the Red River Rivalry leads the way with a pair of potential first-rounders squaring off.

Sooners LT Trent Williams will spend a lot of time taking on Longhorns DE/OLB Sergio Kindle, who is an explosive athlete who plays both from a stand-up position and with his hand in the dirt in passing situations. Williams is one of the best tackles in the country, though, and has the athletic ability to hang with Kindle.

Williams should have the upper hand in the running game with his quick first step and impressive lower-body strength. He outweighs the 255-pound Kindle by 50 pounds and does a great job using leverage and strength to create movement, and Williams is a nasty finisher who will have a big advantage in phone-booth situations when the Sooners elect to run at Kindle.

For a look at how Williams and Kindle match up in the passing game, what to expect when Notre Dame's best offensive tackle and a fast-rising USC defensive end face off, two more intriguing interior matchups and notes from around the country, you must be an ESPN Insider.
