ALLEN PARK — Ndamukong Suh said he wanted to go away from the Lions rookie minicamp weekend with a better knowledge of the defensive schemes and understand where he will be placed on the defense.

“It’s obviously not set in stone, things can always change, but as of right now I have a good idea where I’m going to be and what I need to get done and what I need to work on in these next two weeks,’’ Suh said.

Most of that involves studying the playbook. He’s one of the rookies who doesn’t need to get in shape, he just needs to stay in shape.

The Lions had scouted Suh so well that nothing he did on the field was really a surprise.

Coach Jim Schwartz compared him, in a way, to Matthew Stafford who went into rookie minicamp a year ago as the top overall pick.

“You could see (Stafford’s) arm on film, you could see his decision-making on film, all those things. What you didn’t realize is how hard of a worker he was and his personality and things like that,’’ Schwartz said.

“That’s probably the same thing with Ndamukong is that you get a feel for how serious he is about his business, how much he wants to be a great player. It’s not just show, it’s not just something that comes across in a 15-minute interview or a one-day visit. It’s something that’s real with him.’’
