Close Flex is a Strong I set built around a detached tight end. The fullback stays offset to the strong side and the halfback sits at full depth, but the TE flexes off the line a couple of yards outside the tackle instead of attaching in a three point stance. The two receivers split wide. The backfield stays the same as other Strong I sets, so you keep downhill lead runs, counters and play action, while the flexed TE changes how the defense has to align and who it has to cover.
The flex alignment forces a choice. If the defense treats the TE like a slot and walks a nickel or linebacker out over him, the box gets lighter and FB Dive, Counter Weak and the lead draws hit against a numbers advantage. If the defense stays heavy with base personnel and keeps a linebacker on the TE, that linebacker has to carry him vertically on Mills, PA Lead Draw Shot and PA Boot Slide. That coverage matchup is how this set generates explosive passes out of 21 personnel. The flexed TE also gets a free release with no chip or jam, so he reaches the seam and the flat faster than an inline TE can.
The menu is compact but balanced. You get downhill runs (FB Dive, HB Stretch, Counter Weak), shot play action (both PA Lead Draw Shot versions and PA Boot Slide), a quick passing concept in Drive, a vertical concept in Mills, and constraint plays in HB Slip Screen and PA Sprint HB Flat. The 3DRB, Gadget and Power HB tags fit here: put a receiving back at HB to punish linebackers on the slip screen and sprint flat, or use a bruiser to run the lead and counter game that sets up everything else.
Read the defender aligned over the flexed TE before the snap: a linebacker there means Mills or PA Lead Draw Shot to the TE, while a nickel or safety walking down means you check to FB Dive or Counter Weak against the lighter box.
On first and 10 and second and short, establish FB Dive and Counter Weak early, then call PA Lead Draw Shot from the same look once the safeties start triggering downhill on run action.
Against Cover 3 on early downs, call PA Boot Slide and read the slide first; if the flat defender jumps it, hit the deeper crosser or corner behind him before the backside pressure arrives.
When you see heavy blitz or edge pressure indicators, audible to HB Slip Screen or keep the FB in to block on Drive by hot routing the HB to a block, then throw hot to the shallow cross.
In the red zone, use Drive and PA Sprint HB Flat to flood the short field, and hot route the TE to a fade or corner to isolate him against a linebacker when the defense stays in base personnel.
