If you look at the Air Force pattern reading information that is out there (free) you can study and learn. It is not as easy as some folks make it sound because the strong side reads and the weak side reads are slightly different and of course at the hs level, you get one injury and you might have to flop a kid from strong to weak or weak to strong and bring in a sub whos not skilled at either yadda yadda yadda.
One thing, when you have five underneath zones and vacate two of them, you got holes. If your kids are kinda heavy footed, its probably best to keep them looking at the qb or the qb will pull the ball down and run right by them just as they do when running off defenders in man.
IM playing around with this stuff and hope to test some of it out in our first ever 7 on 7 passing league stuff this summer ....If I can get any kids out. Most of my skill position players are too busy with summer baseball.
