Numbers are always going to be fuzzy, and locations are going to vary - but $15K per year per player as an average cost to the family seems very, very high. Every few weeks someone posts up the same "Wait, so how much does everyone pay" question on all the various online groups, and it sure seems to be closer to $5K for most of the top leagues, with a possible range of almost nothing up to that 5 digit cost you estimated. Of course some can factor in traveling to multiple out of state tournaments, flying with a family of 4, while on the other end there are others who have all direct costs covered by the club and have theoretically nothing out of pocket. Thinking that there is an average of $15K per player, so $300K per team, to allocate in various better ways - seems wildly optimistic. For what it's worth, MLS Next and ECNL parents are paying nothing close to this, in a HCOL area in NorCal.
I wish it was 5K total. With required "donations", fundrsaising, gear and club fees - it's 5K, without travel and extra tournaments.
Once you add the cost of traveling to Arizona, Dallas, Maryland, Richmond, Tennessee, Colorado, Florida, etc with the cost of car rental, hotels, eating out, and flights, it definitely hits another 10K a year because you're also paying for a team of coaches to travel with you. Plane tickets range are bt 300-700 for flights. Hotel rooms range from $200-350 a night. Food is about $50-100 a day per person. Car rental ranges from 200-1000 based on how long the trip is.
Yes, you could split the hotel and car rental, but you can't split the flight and food cost. Maryland, at it's cheapest, was $1400 a kid without any other family members attending. Tennessee cost the girls approximately $1200 for the very basics and splitting everything, without other family members attending. There's at least 3 showcases a year, other tournaments, and finally post-season (which are two very expensive trips because they're long trips due to addition of nonplay days).
That is a total of 15K.
My suggestion is a 10K cost for each player, with a local league and traveling only for 1 national competition showcase/tournament/championship. On a team of 18 players, that's 180K. A coach and club could definitely do some great training, scrimmages, fitness, film review and technical training with that amount of money. This would be better for coaches too because their family would appreciate it.
Suggested Strategy:
Cost=10K club cost
Games= 1 local league game every week and scrimmages if needed (excluding holidays and break periods)
Tournaments = 1 National Tournament per year and unlimited local tournaments as desired
I think this is a win for clubs, a win for coaches, a win for player development, and a win for parent cost/family & personal time.
