Karl Mecklenburg was a tremendous player and one of the interesting aspects of his career is he is credited with playing "all seven positions in the defensive front".
In the late 1970s Joe Collier, the Broncos Defensive Coordinator deployed Randy Gradishar in a similar fashion, though not as much as Mecklenburg. And to be accurate, though Mecklenburg did play all those positions his primary position was inside linebacker in base and defensive end in nickel.
Similarly, Gradishar's position was inside linebacker, and since his forte was pass coverage in passing situations he stayed as a linebacker in those defenses rather than rushing the passer, which was Mecklenburg's strong suit.
So, with that background, here at some screenshots of the various techniques Gradishar lined up at—which totals seven.
|The Broncos did play some 4-3 and in those schemes Graidahar|
was the MIKE, and also in the 33 nickel and in goalline defenses.
|Gradishar as a MLB in a 4-3|
|Gradiahr at RILB in a 3-4|
|Again, RDT, makes this a 4-3 under|
|Here is Gradishar (#53) at RDT to make the Broncos 3-4 into a 4-3|
|Here is Gradishar (#53) at RDT|
|Here is Gradishar (#53) at LDT, again, to make the Broncos 3-4 into a 4-3|
|Stemming into and out of the LDT (3-tech) position|
|Gradishar as the RDE in nickel|
|On occasion, Gradishar would line up over a tackle on the second level|
So, when Collier got his new toy, Karl Mecklenburg, in 1983 he simply expanded what had been done before but is was not really anything new.
