Marcus’s skill roadmap

Where he is now, and the order the pieces should come. Offensive lineman (guard), age 12 — built around the size and toughness he already has, not a generic checklist.

Marcus is a big, strong, willing lineman who's just started winning the leverage battle. The size and toughness are strengths and don't need building. He's held back by the craft: playing too tall, hands that land late, and a slow get-off. This roadmap turns a big body into a real lineman.

The biggest thing in the trenches, and where his size is being wasted.

• Stay-low drive reps — hips sunk, pads under pads, bend the knees not the back.
• Fit-and-drive — feel winning leverage and moving a man.
• One rule every rep: low man wins — get under him and stay there.

The measure isn't a drill — it's a game where he drives a defender off the ball on a key down.

The hands (holding, getting shed) and the slow first step are the next leaks.

• Punch-and-lock — inside hands, thumbs up, on time, every rep.
• Stance-and-get-off — explosive, low first steps on the count.
• Firing off and initiating instead of catching.

A lineman who can pass-pro is valuable on every down.

• The kick-slide — balanced, low, patient, feet not crossing.
• Anchoring against the bull rush.
• Mirroring a rusher instead of lunging.

By next season the pieces combine into a kid who wins the trenches.

• Low pad level and inside hands automatic, even when tired.
• Explosive get-off on every snap.
• Run blocking and pass protection both reliable — and a motor that finishes every play.

Don't chase all of it at once — that's how a big kid stays a speed bump. One horizon at a time, in order. Pad level first, because it's where his size is being wasted and where the trenches are won. Revisit every few months; as one piece locks in, the next one sharpens. And remember: none of this shows up in stats — so the parent's job is to see it.
