Quit with the 3-4 crap. They are running a modifed version of 3+1 on the d-line because they do not have the players for the straight 3-4 as the base D yet. In effect it is a 4-3 much of the time. Most of the season has been played in a 4 man front including a ton of nickel due to the many sprint option offenses they go against.
That is no excuse for bad secondary play. Kids in HS play "quarters" and nickel coverage all over the country. They are just bad. Kids in HS that play LB and safety know how to read O-line blocks and the lead blockers to stop plays on the edges easily. Not our D.
