Now days, zone blocking has taken over as the predominant scheme I see utilized by teams that don't normally produce lineman big enough to do much man on man blocking. I also see tackles pulling all the way across the formation to pick up the defensive end (or whoever shows up first) allowing the play side guard and tackle to double team, then get off to the second level. All can be effective, but whatever happened to the entire offensive line cut blocking right off the line of scrimmage? Permian back in their glory days was notorious for their small lineman dropping bigger defenders all over the field using mass amounts of cut blocks.
This is the 1987 Permian vs. Arlington playoff game.
The thing I find interesting is that both teams do a ton of cut blocking almost immediately, but Permian especially. Even the pulling lineman for Mojo that get to the linebacker or secondary level are cutting guys down field. Has this proven to not be effective anymore?*
*When I played I was a QB, so I know very little about the offensive line schemes.
