If your formation reveals a clear power side, then you're not tipping anything by installing power to only that side.

We did a lot of "dot" when we were running a lot of power. It was more a necessity then a preference.

When we wanted tempo we were no mo and dot helped a lot

I'll be running MH's stuff this fall with my 10u.

We are planning to run Power to the right and Counter to the Left. 

As we get older, or if we are ahead of what I think, Power to Left would be an easy add.

It's about execution and what other run schemes you run.  UBSW teams are very successful running power strong and counter weak.  Mix in Power/Counter with Zone/Stretch and a G Scheme and we are off to the races.

Ever consider running Power to the left and Counter to the right?  Here is my logic:  Most teams put their better defensive players on the left (offensive right).  So, run your power at the lesser players, should be bigger gains.  The 'better' defenders will get antsy and aggressive since they are used to making the tackles... so easier to Counter them.

I'm always trying to out think the kids.  Unfortunately, they are usually smarter than I am...  ::)

Strong and weak is an easier time effective technique then left or right unless your formations doesn't change.

Running power weak is different then power strong..

I didn't mean to imply running Power Weak vs Power Strong... more along the lines of flipping your offense so that you are running Power to the 'weaker' defenders and Counter to the more aggressive, 'stronger(better)' defenders.

Power and Counter have ZERO to do with Right or Left, they are right and left agnostic! Example:

If your are faced with a 43 over and shift from Double > Trips the LB's will shift and you will get fewer defenders away from Trips. In most cases you will get:

1. A gap defender
2. Will backer over the bubble
3. DE 5 tech

This is an easy block!

Example:
1. Start in DOUBLE motion H to create Trips and counter away from Trips!

See attachment (Double ---> Trips)

Take your Simple Six or Sainted Six and teach them to either direction!  Its up to you to determine which ones are well executed and implement those! I am a firm believer in using Misdirection/Counters! 

The Simple Six is a great book. I think pretty much every coach should read it.
