Dooley said Saturday a film review found three main culprits: Players were inexperienced in running a particular type of coverage; communication problems in two-minute situations; and just getting beat on a well-executed offensive plays.
"It was a combination of things," Dooley said. "It's important to know why you did what you did. At the end of the day, we can't give up the number of big plays that we did."
* The Vols have 13 days to fix the breakdowns before the opener against North Carolina State.
"Everybody feels good about the work we've put in and the progress that we've made," Dooley said. "We won't really find out how we're going to respond as a team until we get in that situation. The jury's still out on that."
* Dooley said he didn't think defensive coordinator Sal Sunseri would have to simplify the defense to avoid communication breakdowns, but said there might be a gap in understanding between the regulars and the reserves.
"It's hard in scrimmages when you have so many guys going," Dooley said. "You have two groups: You have these veteran guys, and you have these young guys."
* Saturday was media day at Neyland Stadium. Players posed for photos, including action shots, on the field. Then they went inside for a series of interviews with reporters. All players except freshmen participated.
There was no practice Saturday. The team returns to the fields Sunday at 2:30 p.m.
* Four voters — including the News Sentinel's John Adams — ranked Tennessee in the Associated Press poll released Saturday.
The Vols were 33rd in the preseason ranking, eight spots out of the Top 25. Of teams that had a losing record in 2011, only No. 18 Ohio State is ranked higher.
* Some prospects are experts at collecting Twitter followers by playing to different fan bases. Jacksonville, Fla., defensive end DeMarcus Walker, who is being recruited aggressively by Tennessee and other schools, tweeted this on Friday: "I'm really feelin orange and white lately. Knoxville might need to make some room for me."
Walker is a consensus four-star prospect. Most analysts think he will sign with Florida or Alabama.
* CBS commentator Gary Danielson said he expects Tennessee's game against Florida in Week 4 to be the most important meeting between the two schools in years. Danielson had high praise for the Vols in a CBSSports.com article.
"There are some tremendously gifted players on offense for Tennessee," he said. "If Tyler Bray is who I think he is, he'll have a great year. Tennessee is loaded at wide receiver and has some veterans on the offensive line. This is a highly motivated football team."
