ALLEN PARK — Reggie Bush says It’s too early to tell exactly how the Detroit Lions’ offense will change under new coach Jim Caldwell and offensive coordinator Joe Lombardi.

Bush talked to the media Thursday morning. This is the first week of the offseason workout program for the Lions.

Bush said he’s impressed with Caldwell who talked to the team on Monday about their goals this season.

“(He) just talked about a clean slate, starting over, starting fresh, building that championship mentality. It starts right now, it starts in the offseason,’’ Bush said. “Veteran leadership is going to be important, we’re going to have to keep guys healthy and make sure everyone’s here.’’

While Bush worked with Lombardi at New Orleans, he has not worked with Caldwell previously.

“I really like him a lot,’’ Bush said. “The first meeting we had I was really impressed with some of the things he said and talked about. Really impressive, well spoken, guy  smart you can tell he knows what he’s talking about and excited to work for him ...’’

Bush said they haven’t gotten into the new playbook yet. The first two-week phase of the offseason program involves strength and conditioning.

Whatever the changes even if it involves his workload, Bush seems to be ready.

“Joique’s a great player, I think what me and him have going right now is pretty good,’’ Bush said. “Hopefully we can build on what we put together last year. I don’t  think we’re at all worried about the workload, I think we both work hard enough through the offseason to prepare for a heavy workload.’’

The running game is expected to change with the addition of fullback Jed Collins.

“We had a fullback last year he just got injured,’’ Bush said referring to Montell Owens. “Whatever they call us to do we’ll be ready. Whether it’ less of a workload or more of a workload we’ll be ready.’’
