Mailbag question: Defensive fronts question


Mailbag question: Defensive fronts question

Eroc and Coach,

Can you guys give us folks a little heads up on the different fronts and coverage's used by our defense this past spring?

I guess too much has been made of the "spinner", "quick" and "hybrid" things on defense.

Just would like to have an idea what fronts we are going to run against different offensive formations before the season starts.

If you guys can give a rundown of fronts and coverage's employed it would be great. If you have already dealt with this please let me know which month to look.

Thanks,

Thanks for the question.

Well, first off, please check out the month of April during the spring practices archives under the labels of Coaches Corner, Spring Practice, Michigan Football Tidbits and even sometimes Mailbag questions. That might take up a lot of research time. So hopefully what is below will help and also serve as a refresher.

Michigan used three basic coverages this spring, but UM played mostly cover 2, or two deep safeties. The defense also showed some cover 4, or 1/4 coverage, and some man coverage.

A zone blitz scheme was a key to the coverages that Michigan was playing. There were times when S. Brown was in deep zone coverage and UM also played a version of the now famous Tampa 2 with Ezeh, or another inside linebacker, playing deep coverage.

The defense used two basic fronts to initiate play. Michigan showed a standard 3-4 look, whereby, the nose-tackle played a 0-tech, head up on the center, and the defensive ends played head up on the offensive tackles.

Michigan also stemmed the defense/shifted it down away from the quick, with the defensive tackle playing a 1-tech/outside on the offensive center and the strong side defensive end playing a 3-tech/outside shade on offensive guard, and the quick/hybrid outside linebacker/defensive end lining up in 5-tech/outside shade on offensive tackle.

Remember this was part of a zone blitz package, so where the players started in the alignment is generally not where the players ended up.

Also, remember the players were just initially learning the defense and we are ASSuming that the defensive package will be more complicated and involved this fall as well as during the season. Several of us were on the sidelines directly next to the defensive group and could easily observe that players were very confused on many plays after coming off the field and immediately finding coaches for clarification. This is a new system (yes, another new system). So, understanding that today’s defenses are complicated, one must expect difficulties and grant time for the players and coaches to work out the imperfections.

  1. I guess RVB is the one who is currently slated to play the SDE and the Strong side 3tech....is he going to be able to hold up at the 3tech spot against power teams?? He is only around 270 i guess, that's kinda light for a 3tech.

    Now if Campbell can lose a few pounds and get to like 300-310, then he might be quick enough to slide out to 4/5tech during certain situations (passing downs and against spread teams). This would be awesome...i know he is a freshman and all, but Branch kinda pulled off something similar in 05....your thoughts??

  2. RVB was solid this spring when playing the 3 tech DT. He does nice job of keeping his pads low which helps him against the run. Other thing that helps is this an aggresive, penetrating defense. If RVB was being forced to hold the gap, he would have a tough time succeeding.
