I'm the Juggernaut Biiiiiiach!
LB's, no doubt
the linebackers no doubt
Linebackers and then DL second.
LB's with ease. Also, if Ginn can produce quick this year, and Cam can get something out of Chambers, between Ginn, Chambers, Booker, they could end up a strong unit.
Man Up, Beer Down!
LB by default. I don't think you can call any of those factors a strength other than LB. The D-line used to be spectacular, but losing Kevin Carter will be a much bigger hit than what people expect.
