Middle of the pack. I think people overrate most linebacking corps in the NFL. Fujita/Vilma is as strong of a tandem as you'll fine on any but the top 5 or so LB'ing corps in the NFL (assuming, of course, Vilma is healthy). We just need a WLB to come out of somewhere.
You can't tell me though you'd take 20 linebacking groups over Fujita/Vilma/any marginal starter.
