10 personnel puts one running back, zero tight ends, and four wide receivers on the field, creating the most pass-heavy spread identity in the game outside of empty sets. Defenses are forced into dime or heavy nickel to match the extra receiver, which means lighter boxes, more slot corners in space, and safeties pulled wide to handle the fourth wideout. That substitution war is the real value here: you either get a linebacker stranded on a slot receiver in man or you get a soft box you can attack with draws, RPOs, and QB runs against six defenders.
