Which Air Raid concepts can easily be installed?

Coach,

IMHO......
Y cross is essentially waggle. So, I am sure you already run waggle. However, the AirRaid guys just run it from a 3 step drop out of gun. I think it is probably one of the easiest routes to install and teach.

Y stick is another diverse yet simple concept.
The concept is multiple in that it can be run with playaction "keep pass", as part of your sprint game, and as part of your dropback passing series. Additionally, I would say that it is a pretty universal route. Meaning, it is good vs any coverage. It may not be a deep yardage concept but I feel you can expect to get 5-7 yards every time you run it. Plus, it is very QB friendly!

Hope this helps.

Shallow I think is the easiest to teach. We go to a spread formation when we run it.

We also run Mesh, which we run from 100/900 and its even better from Spread 100/900

The reason I said Y Cross is because it is essentially waggle. There would be very little teaching. It is also a universal route (good vs any coverage) and has automatic hot routes built in.

I also think Stick is very easy to teach from a WingT perspective because it can be run with jet motion and as part of sprint or keep pass game.

Just my two cents worth. All of it is very good!
