Iso

The Iso tag collects downhill, gap-scheme runs built on a lead blocker isolating a single linebacker in the box, spanning plays like HB Blast, HB Lead, Close HB Lead, and their Alert variants across 11 formations and 36 sets. You will find it stacked in heavy personnel looks (Strong I, Power I, Wishbone, Flexbone, Maryland I) as well as Shotgun and Pistol lead concepts, so the same blocking rules travel from goal line packages to spread sets. Competitive players use this filter to build a run identity that punishes single-high man coverage and light boxes, then pair the Alert X Smoke and Alert Z Lookie tags to get a built-in RPO answer without burning a pre-snap hot route.
