The “Isolation” is a running play where the Fullback leads the Tailback through the hole. Most are run inside (between the center/guard), but some are run a bit more outside (between the guard/tackle). It is also referred to as a “lead play”, or is shortened to simply an “ISO”. The Fullback leads the Tailback through the hole. It’s run out of the “I Formation” (QB/FB/TB stacked on top of each other with the QB under Center) and can be run out of the “Offset I”, which is a term that will be tackled in a future post.
The first play showcases the “Inside ISO”. In this example, it is run to the “strong side” of the formation. In this case, the TE and and Z receiver are on the right hand side of the offense with only the X being on the left.
The second play showcases the “Outside ISO” and it is run to the “weak side” of the offense. The ISO is a staple of every offense, even the ones that are pass-heavy outside of the shotgun, simply because there are situations, (short yardage/goal line) where there can be a need for the bruising fullback making a dent into the LOS for the tailback.No tags for this post.
