This is almost identical to some of the stuff I run, only my ILB's are called "Mike" and "Will" and my weakside OLB is the "Rush". That "Under 6" play is something I run frequently.
In the Cover-2, the CB is reading #2. The CB will sink until something shows in the flats. If #2 doesn't go to flat (i.e. he runs inside or vertical) the CB will 'man' #1. If #2 and #1 run vertical then it turns into Cover-4 on that side. If it turns into Cover-4 then the LB to that side of the ball must "expand" with #3 (could be a RB) to the flats.
If Miami's willing to sign a bunch of small, slow white kids then I can provide them with plenty of players who will understand their scheme from day one. LOL
But all jokes aside, you can see why most of our kids are having a hard time. This is alot of stuff for kids to understand, especially kids from South Florida who only run Cover-2 Man for 4 years. You can bet your *** that kids like Artie Burns don't know any of these techniques.
This type of defense will make your kids look super slow if they don't know their reads. Kids who run 4.3 will get toasted because their brain is spinning. For example, a kid like Crawford who runs a 4.4 but can easily get roasted while playing our version of Cover-2. While he's "sinking" in his zone, he's reading #2 and his brain is slowing down just enough for #1 to run right by him on a vertical. On tape it looks like #1 just ran right by Crawford and smoked him, but in actuality Crawford was running slower because he was unsure about his read on #2.
It's a defense that has to be repped over and over and over again, but when the kids get it right it can be very ****.
