My Reply to the

As far as stopping the DW goes, I've never believed that you set up a specific scheme to get it done. At the youth level (I coach HS as well), you need to simply drill your kids over and over to stay home and cover their individual responsibilities. You don't need great athletes, you don't need a clever scheme. If your defensive scheme is sound to begin with (covers every gap, nobody two gapping) then it just comes down to execution. Teach your kids to be great tacklers and to stay home and trust that their teammates will do the same and you can suceed against the DW. I've never lost a game to a DW team in years that I've coached at the youth level. It's not because my teams are loaded up either. We have kids of average size and average speed. We just coach them up on the one great fundamental that seems to get left out more and more these days...TACKLING! A great gameplan is not substitute for 11 kids that can tackle.
On another note, I've run the I offense for better than 10 years. Contrary to other opinions, we don't need horses to score a lot of points. We keep it simple, Iso, Sweep, Inside Trap, Crossbuck, Quick Passes, and a boatload of playaction. The same principals apply, coach 'em up, 11 men for one result, beat all the scheming and crazy gameplans with execution and technique.
