When we moved them to travel ball (at 11U), we were looking for higher quality coaching. To us this meant skill development as well as learning how to play the game with intensity and focus. We also wanted to see better, more consistent competition. These things don't require 4-5 practices a week (plus documented at-home workouts?), and you can see by watching a few practices and games how the team is run and whether or not it's a good fit.
To explain, our LL experience was much the same, dad's volunteering and not knowing much about the game other than what they saw on TV.
We then moved to a local travel team that had a light fall schedule, some Sunday only tourneys in the fall because kids were playing basketball etc, maybe 1 workout a week indoors over winter, then 3 practices a week during spring/summer. This is the type of program I am thinking would be the stepping stone from LL to what we are in now.
Our previous Travel ball team was AA/AAA and we got to experience the full year travel ball at a slower pace than the all out version we are experiencing now. We are at an academy program now, it's pretty much a dynasty in the South, and it's beyond intense...but my kid loves all the practices and usually does 5 home workouts a week, and has asked the coach if he can hold MORE workouts...*shaking my head*...my kid loves it, he is thriving and he is learning proper fundamentals, so as long as he is happy I am happy....I just don't think either of us would have been so gun-ho going from LL to this type of travel ball environment straight away, that was my point to the OP, because from his post I would suspect the team he is considering is much like the program we are in now.
