If you want the best perspective on the Alabama defense, ask someone that has to square off against it every day in practice.

Senior center Bradley Bozeman enters his senior season in Tuscaloosa with more than four years experience facing the Crimson Tide defense. After a little more than a week of fall camp in 2017, what are his impressions of this year's unit?

"They're getting after it," Bozeman told reporters. "They're flying to the ball, trying to get the ball out, strip it out, pick it off, whatever it is."

That aggressive style of Jeremy Pruitt led to a nation's-best 10 defensive touchdowns in 2016. The talent level in Tuscaloosa seemingly gets better every year, which has also raised the level of competition.

"Iron sharpens iron. When you're going against the best in the nation, it's hard not to get better. Either you get better or you get beat, and I don't like to be beat."

With one scrimmage in the books, Alabama still has to get better before the season opener against Florida State.

"There's some things we definitely have to work on. We did some good things and we did some bad things also."
