Most plays are either low-yard gainers or losses or long run touchdowns.
However, since typical play usually has 3 to 4 on one currently, ANY improvement in blocking should show some measurable improvement. I keep telling the kids to try to stay on their blocks for at least 3-4 seconds. If the line could do that as well as any backs not carrying the ball, then we should be able to execute devastating end-arounds. Our blocking, however, more often resembles bump and run with the defender simply bouncing off the block and continuing on his way into the backfield to pressure the quarterback or completely missing a block . I'll let you know how we fared.
