In 94.2 percent of the plays the Volunteers (4-6, 0-6 Southeastern Conference) have been on the field defensively, opponents have averaged just 3.83 yards. However, in the other 36 plays, the opposition is gaining 37.3 yards per clip.
Making teams one-dimensional could go a long way in eliminating those chunks of yardage.
In last Saturday's 42-point loss in Fayetteville, Ark., the Volunteer secondary forced just 10 incomplete passes in 27 attempts. The lone takeaway by the defense came on an interception by middle linebacker Austin Johnson.

Tennessee is the only team in the country with three of its top tacklers being freshmen, including safety Brian Randolph (40).
Vanderbilt quarterback Jordan Rodgers threatens opposing defenses with both is right arm and his feet. Although he has completed just 51.2 percent of his passes, he still possesses big-play ability when out of the pocket and his the team's second-leading rusher (80 carries, 305 yards).
Sophomore Jordan Matthews presents matchup problems for all Commodore foes with his 6-foot-3, 202-pound frame. The Madison, Ala., native leads his team with 29 catches for 569 yards.
