The NFL's itinerant linebacker is unpacking his bags in Arizona.
The Lions' No. 9 overall pick in the 2006 NFL Draft, Sims has bounced around the league as an insurance policy with the Eagles, Colts and Cowboys over the past four seasons. Speedy but undersized and lacking playmaking ability, Sims has been a below-average starter in run support, pass rush and coverage skills.
The linebacker corps has gone from the integral asset in the NFL's No. 1 run defense last season to perhaps its biggest weakness in the upcoming season.
