Generally since there is not much zone pass defense played in MF then you will often see the all out blitzes and man-man press coverage.

I think it also depends on the rule set. Take for instance the shootout rules. In this system the "O" gets three back field motion audibles to only one on defensive audible. In this system you will see a lot of the 8-9 man fronts in order to limit the number of gaps in the defense. In shootout if the D plays a 3-4 defense the offense can motion audible two RBs into DL gaps (or outside the DEs) and the defense with only one audible is like....huh? Now take a rule set like the mid-ohio where defense gets one more audible than the O makes (typically 3 pivots to 2 in favor of defense). In this case you never get caught with your pants down by having a massive hole on your defense because you have enough audibles to react. In this case, you may decide to play LB's with more depth to have beter angles during pivot audibles and if one TTCs these LBs can be disguised to play a short zone (just an example where you may want to play with more depth on defense). Also, any touch vs front of base tackling may require different strategies to stop the run.
