This line has Director of Coaching-speak written all over it. Not trying to yank your chain here. I am genuinely curious about that statement.
Can you define what a track record of player development would look like? I've had lots of experience with clubs that tout such things. They generally post their college commits every year on their website, and keep a running tally of all the great players who have gone on to play college over the years. Funny thing is, that when you dig deeper on each individual player, almost all of them played significant years of their early youth career for different clubs. It's more rare to find a college player who has done their entire club career with just one club. And the other question is the chicken-or-egg argument. If naturally gifted and driven athletes flock together at the same club, is it the club or the players that are creating the "track record?"
"Pathways" and "development" to me are myths. I would love to be wrong about that, but I haven't seen any club that can prove they provide these services. What I have seen is that clubs can provide coaching. Sometimes the coaching is very good and sometimes the coaching is very bad, and very often just ok. And I don't see that any club has a monopoly on either bad or good or just ok coaches. I do know clubs who, from the very top down, try their best to collect good coaches and encourage a certain brand of soccer. But even at those places, they will poach a top player from another club in a heart beat and make no apologies for bragging about their on-field results later.
You make a case for "stability" and argue that parents are the ones disrupting the developmental process by moving clubs. Yet, in the same breath, you say "coaches and players come and go" and it's the "program" that's important to call home. That's DOC speak for, "We're going to shuffle our coaches every year, fire people and hire new ones, so don't pack up your wallet and leave when we fire the one coach you liked, because it's all about the PROGRAM/PATHWAY." In my experience, the smaller clubs generally have a few strong coaches that start with a group of kids usually around U12-13, and coach them year after year until they age out. At the big clubs, the coaching carousel is non-stop. Every year, it's a different coach and some of these guys must have a different colored tracksuit for every day of the week, they've been re-cycled through so many clubs. That's why, my default advice to every parent on this forum is always: Find a good coach first and foremost, and league/level is secondary. But when making these decisions, the club means absolute zero in the equation.
