Pro Football Focus rated Jo-Lonn Dunbar as the third best 4-3 outside linebacker in the NFL in 2012, so we should see some improvement in run defense with him active. Only Von Miller and Jerod Mayo were better. That's the good news. The bad news is he rated as the 111th best linebacker against the pass. That makes him the worst OLB pass defender in the league. Why can't we find players who can walk and chew gum at the same time?
