Bucs 3-4 defense

So if the Bucs used a 3-4 some percentage of the time, is this what it would look like?              David        KwonSpence                              Smith    McCoy    McDonald    AyersWith (other) Spence backing up McDonald, Gholston and Johnson as 3-4 DEs and Howard Jones and Kourtnei Brown at OLB? Or is Johnson too light to be a DE in a 3-4?
