New head coach Jim Caldwell has changed parts of the Lions' offense, bringing in his experience from his time with the Indianapolis Colts and the Baltimore Ravens.
"I played in the system five years in New Orleans so all the terminology's pretty much the same to me," Bush told reporters.
"We definitely have what it takes to be an explosive offense, just as we were last year. Just got to clean up doing the little things right and we'll be okay."
The Lions finished with a 7-9 record last season, missing the playoffs for the second straight season.
