You are missing the point. It is a high cost "league" so run it that way. Or to your point, just get 4 or 5 teams together to chip in and rent space and play organized scrimmages. Which is probably better for and play time, cost and development. Seriously why can't 4 to 5 coaches get together and do that. Give me a day and I'll get the space, tell you cost per head, and give you a schedule from now to March. It will be a lot less money, more playing time and probably a better use of time.
