Lambert was the prototypical middle linebacker for what became the Tampa Two defense. Bud Carson, in his "Double-Rotating Zone" defense where safeties played back in a two-deep zone and the corner-backs played in two shallow zones or in bump-and-run coverage, instead of having the middle linebacker close to the line in run support, had the middle linebacker drop back into a middle zone to cover the seam between the safeties. Middle linebackers had not been tasked in such a way previously (Dick Butkus and Ray Nitschke being the epitomes of the run-support middle linebacker), but Lambert's size, speed, and talents facilitated the new role.
