Man to Man =Trouble in my leauge. Man coverage can be effective depending on the formation. If the offense is spread out, man coverage can be very effective if you have the athletes to match up. I coach 6-8 graders and some teams have kids so fast and quarterbacks so accurate that zone simply doesn't work. We go man to contain the other teams best athletes with our best athletes and pressure the QB. If the offense is spread out, the throws generally have to travel farther so if we can keep those players covered a little longer and bring pressure, it can cause inaccurate passes. The risk with man is you're susceptible to runs, but at this level, you don't see end arounds or reverses anymore. Most of it is spread passing formations.
