Blocking a field goal???

We have had pretty good success blocking field goal/x-pts by attacking th A gaps. We align two defensive lineman in 1 techniques and tell them to attack the guards from inside out and try to create a gap for two linebackers to rush through. The linebackers need to make themselves small as to not touch the snapper. We have blocked 5 x-pts this year and have not seen any field goals attemted on us. Hope this helps.
