AFL Round 21 2026 Team of the Week: Thilthorpe and McKay rated the same — one wears the jumper, one doesn't
Round 21 was a blowout, and blowouts don't spread talent evenly — they flood one line and starve another. Riley Thilthorpe and Harry McKay finished level on the biggest number in the competition; only one made the eighteen, and the reason is the whole story of how a Team of the Week gets picked.
The read
Round 21 was a blowout round — four results decided by more than a converted-goal-a-quarter, the kind of week that leaves the ladder looking like a highway with two speed limits. Weeks like that don't spread talent evenly across the team sheet. They flood one part of it and starve another. This week, they produced two centre forwards with the identical share of their team's scoring work. One of them is holding a Team of the Week jumper. The other is not.
Riley Thilthorpe and Harry McKay finished Round 21 rated the same — level on the single biggest individual number in the competition. Thilthorpe starts at centre-half-forward. McKay watches from home, level with him on paper and nowhere on the team sheet. If you think that's a misprint, you have found the whole essay in one line.
It isn't a misprint. It's the point.
The team is not built by lining up every player in the competition and taking the top eighteen numbers. It's built by role — a full-forward slot, a centre-half-forward slot, two wings, a specific number of key defenders — and each player only ever competes against the handful of others doing his exact job that week. Thilthorpe's 228 beat every other centre-half-forward in the country. McKay's identical 228 ran into a year when the key-forward posts were simply oversubscribed — Brodie Kemp's 213 at full-forward, on the day Carlton put 154 on Brisbane, got there first. Two forwards, same number, one empty chair between them. Not injustice. Arithmetic.
That's the part a scoreboard-only read of Round 21 misses entirely, and it's the reason the conventional take on “who had the best game” keeps landing in the wrong place. The instinct is to treat rating as a queue — biggest number goes first, next biggest goes next. It isn't a queue. It's eighteen separate small rooms, each with a strict headcount, and a player only ever gets measured against the others trying to get into his room. Carlton found that out the hard way. Their 76-point demolition of Brisbane produced four rated performances that would have started most weeks — Kemp, George Hewett, McKay, Will Hayward — and the room for key forwards only had two doors. A club can win going away and still lose the argument for its own depth, because the ceiling isn't opponent quality. It's slots per room.
Sydney supplied the same lesson from a different angle. Errol Gulden and Chad Warner both start in the midfield this week — Warner for the tenth time this season, the only player in the competition to reach double figures. But the highest-rated Sydney player of the round isn't either of them. Isaac Heeney's afternoon out-scored both his teammates and still didn't make the eighteen, beaten not by anyone in claret and gold but by six other clubs' midfields all peaking in the same seven days. Heeney did nothing wrong. The room was full before he got there.
There's a smaller, quieter version of the same idea sitting at full-back. Harrison Petty carries the lowest number in the entire team — by a distance — and it isn't close to the worst game in it. Key defenders are marked down by design, because stopping is a harder thing to count than scoring, and a defender who does his job invisibly will always look worse on paper than a forward who does his job in the open. Petty's number says almost nothing about his Sunday. His third selection in five weeks says plenty.
Which is really what the whole round is arguing, if you let it. The rating is not the call. It's the raw material the call gets built from, room by room, against the specific handful of people trying to do the same job on the same day. Thilthorpe and McKay didn't have different Sundays. They had the same Sunday, filed into different-sized rooms. One had a spare seat. The other didn't. Everything about how a Team of the Week actually gets picked is sitting inside that gap — and none of it was visible from the number alone.
Who ran out of jumpers
The measure of how big the round was isn't the eighteen who made it — it's the players who produced genuine Team-of-the-Week football and still missed.

The team is picked room by room, not by the biggest number: Thilthorpe and McKay both rated 228, but the key-forward posts were oversubscribed and only one chair was open — this is best-in-role, not top of the queue.
