When Half of Liga MX Wants a B-Team

In Guadalajara there is a training ground that hums with the sound of the ball every afternoon. I sat there for three straight days during a reporting trip in February, and what caught my attention was not the play itself but the way the young players called each other — by shirt number, not by name. One boy born in 2026 was called "Eleven"; another was "Twenty." They had no name in the first team yet, but they already had a number. That is how a B-team exists: you are numbered before you are named.

A few days ago, the Mexican outlet RÉCORD reported that half of the clubs in Liga MX have formally requested to create affiliate teams in Liga de Expansión, the country's professional second tier. If true, half a league asking at once for a B-team is worth pausing over. Not because the number is large, but because it arrived after a single name: Tapatío.

Tapatío is Chivas Guadalajara's reserve side. In the words of the Mexican Football Federation (FMF) and Liga MX, it is the "flagship." Starting this season, a Liga MX club may send its youth squad down to play in Liga de Expansión, where 18-to-22-year-olds face experienced professionals week after week, in real stadiums, with real crowds and real pressure.

The underlying idea is clear: competitive minutes against seasoned footballers develop a young prospect better than a closed U-23 tournament. Mexico did not invent this. Spain has done it for years with B-teams in Segunda B and Primera RFEF. Germany has its U-23 model in the Regionalliga. Mexico is following a proven trend, not creating a new one.

But one detail is more telling than the half-league figure. Initially, the FMF and Liga MX proposed a mandatory plan. Then they changed it to a staggered scheme — meaning no one is forced. Clubs that want to join must prove they have infrastructure, financial solvency, and a squad deep enough to sustain a development team. Those who do not wish to, or cannot afford to, may keep association or loan agreements with traditional Expansión clubs.

This is where I want to linger, because it says more about how football works than the news item itself.

The shift from mandatory to voluntary is a political signal. If the FMF could have forced it, they would have. Their retreat shows that a share of Liga MX clubs objected to the financial burden of owning a full second-division franchise. That cost is not small: stadium rental, travel, staff, wages, and an entire medical and performance department. The plan's "financial solvency" condition is an acknowledgment that this is a real investment, not a game.

The more interesting question is motive. When half the clubs ask for an affiliate at the same moment, it is hard to believe all of them are acting on deep strategic conviction. More likely, some are acting because rivals are. Herd behavior in football is nothing new. It explains why the requests arrived together, after Tapatío was labeled the "flagship" — not after data proved Tapatío truly succeeded.

And this is the crux: no data proves it. There is no promotion rate, no minutes-log for young players, no count of players promoted to the first team, no comparison with other academies. Tapatío is called a success, but that success has not been measured. In my trade, a name repeated many times does not automatically become a verified fact.

That gap between narrative and data matters because it shapes how we should read the report. If half of Liga MX is joining out of herd behavior, the odds of affiliate teams being created before they are organizationally ripe are very real. When an affiliate is built in haste, the ones who pay are not the executives but the young players — placed in an unstable environment and judged on matches their team cannot compete in.

Outside Mexico, it is easy to read this story as a sensible step forward: a larger second tier, more minutes for young players, a more connected pyramid. But there is a counter-view that I consider more important.

First, the model may not suit every club. If Tapatío has succeeded, the Liga de Expansión format is only part of it. It succeeded, in part, because of Chivas' peculiar recruitment policy: only Mexican players, with a strong youth emphasis. A club that copies the format without that identity may get far weaker results. The format is the shell; the philosophy is the core.

Second, there is an unanswered question about promotion. If a Liga MX affiliate wins Liga de Expansión, will it be allowed to play in Liga MX? The report's language — about "maintaining the shield of direct access to Liga MX by purely sporting merit" — suggests this is still being negotiated. The "shield" may well be designed to reassure Liga MX owners who do not want automatic promotion to affect their commercial value. If so, this is not an open pyramid but a controlled one.

Third, stand-alone Expansión clubs risk losing status. When Liga MX affiliates arrive with better resources, wider scouting networks, and clearer first-team pathways, they will draw away the best young players. Traditional clubs may be pushed from independent entities into development partners — no small shift in identity.

I do not think the plan is wrong. A system in which Liga MX academies, Expansión affiliates, and the lower divisions are connected into one pathway for young players is something Mexican football has lacked for years. The problem is pace and transparency.

What I want to track in the coming months is not the half-league figure but three concrete things: how many affiliate teams actually pass the infrastructure and financial test; how many young players reach the first team thanks to Expansión minutes; and whether an affiliate is ever allowed to be promoted. Those are the signals that will tell the truth, not the "flagship" label.

Between two whistles there is a world the scoreboard cannot measure. The emptiest stadium still has a breath; you just have to listen with your heart. In Guadalajara, I heard it — in the way those boys called each other by number, before they were called by name. Football never owes us a result; it only owes us a story. And the story of Tapatío, so far, is still waiting to be finished.
