Ask a football coach about areas of concern and you'll usually get the same response.
"You're concerned about everything going into preseason camp," Navy defensive coordinator Dale Pehrson said.
Pehrson acknowledged that returning starters such as inside linebacker Micah Thomas and outside linebacker D.J. Palmore are proven commodities, but noted that he's seen many players backslide over the years.
"It's a whole new season. Guys can go up and guys can go down. Sometimes they lose focus," Pehrson said.
While it's normal for football coaches to be paranoid and worried, the reality is that every team has its strengths and weaknesses.
