Haha, that cartoon is great.
The travel team my son player for, he was late to baseball starting to play at 12 or so, playing travel ball starting at 14....they enforce pitch counts and play one tournament per month. Buy the time they hit the 19U team they play a ton, 62 games or so over a two month season, but again, they carry a lot of players. We chose them based on the play schedule of once a month when we were starting. Part of that is where we live. Most tournaments are 4 + hour drives, so, they know most people are not going to do that every weekend.
Anyway, they charge $85/mnth. Two practices a week one tournament a month (which usually costs extra, but not a ton, cost includes hotel room). They do not have a gym or a workout area in their facility, but, players do have unlimited access to their facility to work. Here is the thing. Almost always it is virtually empty of guys doing extra work. Most kids just don't want to work that hard.
The option of having a full staff....trainer, PT, a full gym/training facilities and the ability to supervise or do programming for kids, well, the cost would skyrocket. So, I get why they don't do it. So, 9U--17U and two 18U teams with an average of 15 players at $85/mnth to provide access to a building with cages etc and lessons for those so inclined....pretty nice model.
I love the idea of a "team" that is for offseason training. I would love to do that, but, where I live at least I don't know if there would be enough interest to sustain it.
