Senior linebacker Herman Lathers sees a ''night and day'' difference in how the Volunteers are adjusting to the new 3-4 scheme installed by Tennessee first-year defensive coordinator Sal Sunseri.
Lathers said players had trouble in the spring just lining up correctly, but a summer's worth of film study and visiting with position coaches has Sunseri pleased with the defense's progress.
Sunseri still wants players developing toughness and working on fundamentals.
The Vols struggled to get pressure on opposing quarterbacks last season and Sunseri said the pass rush ''isn't where it needs to be'' but is improving.
Wednesday is Tennessee's first full two-a-day practices of fall camp. The Vols took to the field in the morning and will have another practice session in the evening.
