Bush said that Peppers was one of the strongest and most athletic defensive players in the league, and combined with Clay Matthews on the other side the Packers would be hard to beat.
"I think JP, pound-for-pound, is one of the most athletic athletes in the league right now," he told the Green Bay Press Gazette.
"He's definitely a force to be reckoned with. I think with Clay and the whole gang, I think we'll be a championship-calibre team."
The Packers finished with an 8–7–1 record last season.
