He was second on the team with 58 knockdowns during the regular season, recording five or more knockdowns in six games.
As a freshman Caldwell was one of the top freshman offensive linemen in the country. He played 772 snaps and earned Freshman All-SEC. He played most of the season as a guard before moving to center for the 2006 AT&T Cotton Bowl.
The Rimington Trophy is an eight year old award presented by Canon, Cornhusker Marriott and Logitech. The award is hosted by the Boomer Esiason Foundation.
West Virginia's Dan Mozes, Minnesota's Greg Eslinger, Michigan's David Baas (2004 co-winner), LSU's Ben Wilkerson (2004 co-winner), Virginia Tech's Jake Grove, Miami's Brett Romberg, Ohio State's LeCharles Bentley, and Nebraska's Dominic Raiola are past recipients.
Esiason created his foundation in 1993 to support research and treatment of cystic fibrosis. Esiason and Dave Rimington were teammates on the Cincinnati Bengals from 1984-87. Rimington, the award's namesake, was a consensus first team All- America center at Nebraska in 1981 and 1982 during which he became the John Outland Trophy's only double winner as the nation's premiere college interior lineman.
The winner is selected by determining the consensus All-America center pick from four existing All America Teams, including the American Football Coaches Association, Walter Camp Foundation, Sporting News, and Football Writers Association of America
The center with the most first team votes will be determined the winner. If there is a tie with first team votes, then the center with most second team votes will win. If there is still a tie, the winner will be determined by the Rimington Trophy committee.
The winner will be honored at an awards banquet at the Rococo Theater in Lincoln, Nebraska in January, 2008.
Caldwell is one of 20 juniors named to the list of 47 preseason candidates.
