Tom Kowalski, of Mlive.com, reports the Detroit Lions are expected to continue rotating LB Ernie Sims and LB DeAndre Levy Week 9, but playing time could be determined on who is playing better. Sims performed well late in the team's Week 8 game. Defensive coordinator Gunther Cunningham said, "He made some really good plays, and I hadn't seen him do that stuff. Ernie knows the scheme in the classroom and the walk-through situation and even in practice, but he's had some short circuits in the game where he didn't move fast enough because he didn't trust it. All of a sudden during the game -- and everybody on the staff saw it -- he made one play that was unbelievable. I hadn't seen him tackle that way at any time last year or this year, so I feel good for him. That was a good sign."
