Here's a look at OU's freshman class, listed from least likely to most likely to redshirt:
1. Trey Millard, fullback: Brent Venables calls him "a load." The Sooners call him their starting fullback.
2. Kenny Stills, wide receiver: The groin pull was a setback, but Stills has returned to practice and is still a favorite to start.
3. Tony Jefferson, safety: Jefferson is the defense's starting nickelback heading into the opener.
4. Aaron Colvin, cornerback: The Owasso native is on the two-deep at field cornerback behind sophomore Demontre Hurst.
5. Corey Nelson, linebacker: Will help on special teams while learning weakside linebacker from mentor Travis Lewis
6. Bronson Irwin, guard: Backing up Tyler Evans at right guard.
7. Austin Woods, center: Expected to handle the field goal snaps.
8. Joe Powell, wide receiver: Big-play threat capable of playing in the slot or the outside.
9. Trey Franks, slot receiver: Adds breakaway speed to the receiving corps.
10. Daniel Noble, defensive tackle: Pleasant surprise up front, Noble will hold a spot in the rotation until Adrian Taylor is healthy.
11. Austin Haywood, tight end: The best receiving tight end the Sooners have, but needs to work on blocking.
12. Brennan Clay, running back: Versatile playmaker, could help the Sooners at running back, slot receiver and kick returns.
13. Roy Finch, running back: Was going to play, but recent hairline fracture in ankle could change that, especially if injury lingers for more than a month.
14. Justin McCay, wide receiver: Raw at wideout, but McCay's top-notch athleticism could be unleashed on special teams.
15. Blake Bell, quarterback: Drew Allen appears to be the No. 2 QB, meaning the option to redshirt Bell is on the table.
16. Geneo Grissom, defensive end: Solid prospect, but happens to play a position where the Sooners are loaded.
17. Adam Shead, guard: Shead not in the two-deep, but could get time if OU runs into injuries up front.
18. Quentin Hayes, safety: Good-looking prospect who could be utilized in special teams.
19. Aaron Franklin, linebacker: Could help on special teams.
20. Rashod Favors, linebacker: Could also help on special teams.
21. Julian Wilson, cornerback: Colvin appears to be the only freshman cornerback who will play for sure, but Wilson could get on the field by showing he can cover kicks, punts.
22. James Haynes, cornerback: Like Wilson, Haynes could get on the field in special teams, but the Sooners are apt to redshirt some of their defensive backs.
23. Eric Humphrey, defensive tackle: Even with Taylor still working his way back, the Sooners have more experienced options at defensive tackle.
24. Damon Williams, defensive tackle: Even Gerald McCoy redshirted as a freshman.
25. Torrea Peterson, defensive tackle: See Humphrey and Williams.
26. Chuka Ndulue, defensive end: Too far down in the pecking order at end to not redshirt.
27. Tyrus Thompson, offensive tackle: It's almost unheard of for offensive tackles to play as true freshmen.
28. Daryl Williams, offensive tackle: See Thompson.
29. Sheldon McClain, wide receiver: Still working his way back from last year's ACL surgery, and the Sooners have plenty of options at receiver.
