Try kicking off from a hash to squeeze the return team a bit. Plus as Coach Easton said you need to put solid kids in the middle (I put 2 I know he said 4). These are kids who have both speed and size and WHO WILL NOT SHY AWAY FROM Contact! When teams run Middle returns on you its because your players are running around there wedge/wall. I have 2 Kids on the flanks who's responsibility is to speed through the first line and break up the back wedge as it forms, then may 2 TANKS in the middle who break up or stop that middle-front line. If these 4 guys can occupy 6 blockers you've destroyed the middle return.
The double wedge middle return is used often b/c its the easiest to coach, but if the kids have courage it's also the easiest to stop.
