Most of you know me as a long time 46 coach.
Previous to my long lasting love affair with the 46, I had been a multiple 7 and 8 man front coach with the best success coming from coaching the Tom Simonton style 44 stack defense. Since 2008 however, I have blended in some 353 stack defense into our arsenal.
This is by far the single most important lesson I have learned as a high school coach...
1) examine not only your starting personnel but your depth and backups when choosing a base defense.
2) teach a multiple defense with a very good understanding of that base so you can play it when the injury/eligibility issues come up (and at the small school level, they will kill you). Run your base at the feeder levels (our jr high runs a 53)
3) When going multiple with the defense, rep the daylights out of it with the starting unit while the backups continue to get work in the base defense. Youll waste practice time trying to get your 3rd and 4th teamers to rep stuff you might only run 15% of the time.
When the injuries happen, and they will, youll have to be more vanilla but your backups will step in with some level of success.
So, what does this rambling mean? Ill give you an example, we have, on paper, a nice 46 Gambler lineup for this coming season....but we cannot afford one injury to either defensive end or our sam, mike or will or we could not run the 46.... but we feel we can still run the 353 stack with some level of success. We will teach and rep the base to all, teach our 46 looks to our top dawgs and spend the rest of the time getting better at the "bring it" and pursuit/hustle part of the game.
The plan then becomes to base the PROGRAM around the 353 for both varsity and JV and examine the talent each year to see what MULTIPLICITY we can run from that. Ie, the 425, the 46...etc.
I feel that every year I have coached hs football I could find the kind of kids that we might need to play a 353. The spur positions are filled right now by linebacker types, not dback types and our inside guys are all classic okie fifty front plugger types...eventually, Id like to have kids built like my spurs playing inside and faster kids playing on the edge...essentially we have 53 personnel playing a 353. But we have 5 spread teams on teh schedule. I find that we can also use personnel substitutions at times. Ie if we want to go man up with the spurs, I can probably sub in some cover guys to take their spots.
our dbacks are diminutive and looking at the top teams in each class, the better teams have linebacker size kids who can run playing corner and safety, we do not yet have that.
IN any case, I know its obvious but you have to truly consider your PEOPLE when choosing your base and then be multiple based on that. Its really not much different from offense in that your playbook should reflect getting the ball to playmakers.
