canyoncoach What exactly are you looking for?What you have described is basically like how most of the HC's I've work for; to some degree or another. And it worked.
The HC I work for now does the V/JV/9 totally different but we have more coaches (because..... well just because). So we don't have
'Varsity', 'JV', 'Freshman' coaches. We are all 'Varsity' coaches.
We split the team (similar numbers) into an 'A' group and a 'B' group. Now we have fields up the wazoo, so we can have each on their own field....
But the 'A' group is comprised of:
1-varsity starters
2-varsity depth
3-sub-varsity players that need to fill in a 2 deep rosters
4-and this 'A' group does not mean that they you automatically dress on Friday.... so there are swing players
The 'B' group is purely developmental players.... so mainly freshman and the remaining JV. They mostly spend a lot of time in team type periods, but have some Indy and inside periods.
For M/T/W the A/B groups don't change (except for a very few players that rotate), but the coaches rotate. So the 'B' group always have a varsity coach working with that position for the entire day.
The coordinators always stay with the 'A' group and there are certain coaches that have to pull double duty (IE LB coach coach his group, but also act as the opposing team DC in offensive periods so his 'B' day is split between fields..... etc) but the HC can float between the 2 groups based on what period is going on and where he is needed.... also we're a school that the HC doesn't have to be a coordinator.
So far as the sub-varsity games (Thursday JV and freshman) there is no set staff. All coaches rotate between each team group from week to week..... except that the HC will rotate a couple of redundant coaches to an off night from time to time which is nice. And also which coach calls the offense/defense on the sub-varsity games rotates as well. So there is no JV DC/OC/HC for the entire season. Basically it's each and every AC will at some point in time during the season have serve a lead role.
It can seem very confusing, and it took me a whole season to figure out how it works but it does... really well.
