One thing that I'm sure everyone is aware of but worth mentioning in this converstation are the following factors.
What level of play does your team participate in? Rec, Select, Premier and also what levels of each of these?
What time of year it is? Spring, Summer, Fall, Winter
If HS age is it your HS season?
Is it for tournament preparation? Summer tournaments? State Cup?
What sort of work ethic does your coach and team have and what the family will support. Is your coach away on business? Family vacation times?
Are you dealing with injuries or fatique.
What the weather is like.

Not so much but I'm sure it is a factor at some levels.
Does your coach think fitness should be a part of practice?
Are there any other factors?
Right now my DS's B94 team (just promoted to Div 1 of RCL) is getting ready for Puma Pacific Coast Challenge.
Here was schedule over last week and this week. This Tuesday included a timed 2 mile fitness test. Players are expected to handle fitness on their own and get ball work in on their own outside of training. No designation on how much but the level of play expected is known and they should figure out how much time they need to put in. Starting league I expect minimum 3 days a week for 2 hrs each session. Not sure if the coach will do more.
