Too many parents are blinded into thinking that playing on the “A” team will accelerate development simply because they’re playing against the “elite” players.
If development is what is truly desired, then they would select a team (regardless of club) that trains twice as much than the “A” team of any other club.
Development occurs mostly during proper trainings, not games. The proper training ratio should be 4:1, not the other way around. If your “B” team trains four times a week, and the “A” team trains two times a week, then the “B” team would be better choice for individual player development.
In my experience, “A” teams mostly do not develop - they recruit. They entice parents with shiny objects and bells and whistles and recruit the players who were developed elsewhere and palm them off as their own. When those players finally make the “A” team, their development trajectory flattens to the same pace as the other “A” team players.
Most “A” teams train just twice a week, or possibly three times a week. If they do train a third day, then that session is usually nothing more than Speed & Agility, which does nothing to develop technical ball control.
