Hi-Lo Passing Concept

The Hi-Lo concept teaches quarterbacks to isolate a single defender by placing one receiver above him and another below him. Rather than reading an entire side of the defense, the quarterback simply reads one player’s movement and throws to the receiver he cannot cover.

Why Hi-Lo Works

No defender can effectively defend two receivers separated vertically. If the defender sinks with the deeper route, the underneath route becomes available. If he attacks the short route, the deeper receiver opens behind him.

Best Formations

Doubles is an excellent teaching formation because it naturally creates balanced spacing. Trips formations add an additional receiving threat while keeping the quarterback’s progression simple.

Personnel

11 Personnel is the preferred starting point, but the concept adapts well to 10 Personnel and formations featuring an athletic tight end.

Route Responsibilities

Outside receiver: Intermediate curl, comeback, or corner depending on the variation.
Slot receiver: Quick flat, hitch, or shallow route.
Backside receiver: Dig, slant, or post as the secondary progression.
Running back: Protect first before releasing as the outlet.

Quarterback Progression

Locate the conflict defender before the snap.
Read his first movement after the snap.
Throw high if he drives downhill.
Throw low if he gains depth.
Take the outlet instead of forcing a contested pass.

Coverage Adjustments

Cover 2

Attack the space between the cornerback and linebacker.

Cover 3

Read the curl/flat defender and throw opposite his leverage.

Man Coverage

Trust route timing and deliver the football before the receiver breaks free.

Quarters

Accept underneath completions and stay on schedule.

Coaching Points

Teach receivers exact route depths.
Quarterbacks must read defenders, not favorite receivers.
Throw on rhythm.
Every complementary route should create space for the primary read.

Common Youth Mistakes

Both routes breaking at similar depths.
Quarterbacks predetermining the throw.
Receivers drifting after their break.
Ignoring the checkdown.

Installation Progression

Teach the upper and lower routes separately, combine them against air, add a single read defender, then progress into 7-on-7 and full-team periods.

Practice Drill

Assign one defender to the conflict area and vary his reactions every repetition. Quarterbacks should announce their read before each throw to reinforce decision-making.

Youth Coaching Tips

Use cones to mark route landmarks during early practices. Once players consistently hit their landmarks, introduce live defenders to teach the progression.

Why Hi-Lo Succeeds

Hi-Lo succeeds because it simplifies quarterback decision-making while forcing one defender into an impossible choice between two receivers at different depths.
