Top 10 offensive linemen in NFL draft

1. Anthony Castonzo, Boston College, 6-7, 311: He made a school-record 54 consecutive starts for the Eagles. He is considered an elite pass protector, who will need to get more push as a run blocker at the pro level.

2. Nate Solder, Colorado, 6-8, 318: He was the Big 12's offensive lineman of the year and a finalist for the Outland Trophy. He had 142 pancake blocks last season and received a 94 percent grade from the coaching staff.

3. Tyron Smith, USC, 6-5, 307: He was named the Pac-10's top offensive lineman after starting 12 games at right tackle. Some consider him the best athlete of the tackle group.

4. Gabe Carimi, Wisconsin; 6-7, 316: He was an all-American and winner of the Outland Trophy, which goes to the nation's top offensive lineman. He keyed the Badgers' power running attack with bone-rattling blocks. He's the classic road grader.

5. Mike Pouncey, Florida, 6-5, 305: A versatile performer who hopes to follow in the footsteps of his twin brother Maurkice to the pro level. He struggled early last season with his shotgun snaps, but made progress over the course of the season.

6. Will Rackley, Lehigh, 6-3, 309: He started all four years for the Mountain Hawks after playing at Riverdale High. In 2010, he was named to the all-Patriot League team for the third consecutive season.

7. Derek Sherrod, Mississippi State, 6-5, 319: After taking over as a sophomore, he became a fixture at left tackle for the Bulldogs. He had good feet and is considered a left tackle prospect.

8. Danny Watkins, Baylor, 6-3, 312: He is from Canada and played hockey and rugby in high school. He went to junior college to become a fireman and ended up playing football at Butte (Calif.) College.

9. Clint Boling, Georgia, 6-4, 307: The Chattahoochee High graduate finished his career with 49 consecutive starts for the Bulldogs. He played right guard, right tackle and left tackle for the Bulldogs. His versatility served him well at the Senior Bowl, where he played both guard and tackle.

10. James Carpenter, Alabama, 6-4, 320: He played at Hephzibah High near Augusta before starting his college career at Coffeyville (Kan.) Community College. He started 27 consecutive games for the Crimson Tide, including all 14 on their march to the national title during his junior season.
