The fly sweep doesn’t die in the backfield.
It dies on the perimeter. A corner who crept to four yards and never got cracked. A 3-4 outside backer the offense didn’t have an answer for. An H-back with his eyes locked on a defender someone else already had, while two more flowed underneath and made the tackle.
Coach Tom Yashinsky teaches the install with that in mind. The line work, the perimeter rules, and the formation menu are all built around one idea: don’t let the play die in the second yard.

The Two-Call System: Linemen Don’t Need to Know It’s Fly Sweep
Coach Yashinsky signals two calls into the huddle. One to the linemen. One to the skill guys.
The linemen and the skill guys are looking at a different guy. The piece a lot of coaches miss: those calls don’t have to match.
“It doesn’t really matter what play we’re running in behind them,” he says. “They block what’s called.”
That means the linemen can be running power or GT counter up front while the skill guys are running fly sweep on the perimeter. To the defensive line and the linebackers, the picture is a power read. To the corner and the alley defender, the picture is a sweep. The defense gets two different keys and has to pick one.
Most of the time, Coach Yashinsky stretches everybody to the play side. That’s the base. The power and GT counter calls are the wrinkle he goes to when the defense is good at reading and he wants to muddy the picture. He shows clips of both in the clinic, and the moment the line work flips from a stretch to a counter is the part most coaches will want to slow down on.
The Crack Rule: Five Yards, Tighten Down
The perimeter rule is one number.
If there’s a threat inside of you closer than linebacker depth, you tighten your split and crack him. Coach Yashinsky puts a number on linebacker depth so his receivers don’t have to guess. Closer than five yards.
Inside of five, the receiver cuts his split and goes get him. Beyond five, he holds his split and the back out of the formation has him.
The reason is the play itself. “If they penetrate inside, it’s going to kill the play.” A defender shading inside the receiver with downhill depth gets to the mesh before the sweep man does. Cracking him is the only answer.
The hardest version of that picture is the 3-4 outside backer. Coach Yashinsky calls those guys the front that gives them the most trouble. They creep up, they sit on the edge, and if the receiver doesn’t recognize the depth and cut his split in time, the play is dead before the handoff. He walks through the look on tape and shows the moment a receiver should recognize the creep and adjust his alignment pre-snap.
Landmarks, Not Locks: Aim Where They’re Going
The running backs and the H-backs have a different job. They’re not assigned to a man. They’re assigned to a landmark.
The rule is short.
- Aim for where the defender is going, not where he is.
- If your guy gets picked up, work to the next one.
- Keep your feet moving. No holding.
The mistake Coach Yashinsky coaches against is the eye lock. The H-back picks out his man, the man gets picked up by somebody else, and the H-back is still running at the same body. While he’s stuck on that defender, two more flow underneath untouched.
The fix is the same coaching point he gives the linemen. Aim for the spot. If the defender’s not there, the spot moves to the next threat. The eyes stay open. Coach Yashinsky shows the rep in the clip and points out the back who does it right alongside the back who locks on. The cue he gives in the meeting room is the part you’ll want to lift verbatim.
The Formation Menu: Condensed, Empty, Unbalanced
The base is condensed.
Coach Yashinsky says it’s his favorite thing to run it out of, to the point where he has to talk himself into other looks so the tendency doesn’t tip the defense. Condensed sets get the receiver into crack range without having to cheat his split, and they make the arc block on the alley defender clean.
Empty is the look most coaches throw out of. He runs out of it. The defense is expecting a five-step drop and gets a sweep instead. He shows variations of empty in the clip that he runs the fly out of, and which alignment he prefers when he wants to attack a specific edge.
Unbalanced is the one that opens a door most defenses don’t expect.
The benefit on paper is one more blocker. The real benefit is the sweep man. In a two-receiver formation, the defense knows the offense can’t run fly sweep away from the receivers. By unbalancing, stepping the backside tackle off, and bringing both receivers to the same side, Coach Yashinsky now has a receiver on the unbalanced side who the defense doesn’t expect to ever be the sweep man. That receiver becomes the ball carrier.
He walks through the formation on the board in the clip and shows a second unbalanced look with a tight end added in and two blocking backs on the perimeter. The double blocking back version is the one he flags as the favorite from the past few seasons, and the reason has to do with how the perimeter numbers shake out against the defenses he’s been seeing.
The trade-off he wants every coach to hear: more blockers means more potential missed blocks. Don’t add an unbalanced set because it sounds good. Add it because you know what the extra body unlocks.
The fly sweep install isn’t a single play. It’s a line call, a perimeter rule, a landmark cue, and a formation menu, and each piece has to be coached on its own before the play hits on Friday. Coach Yashinsky builds it that way because that’s where it breaks when it breaks, and the install is the answer to the breakage.
