Wolf, I've coached rec league soccer and especially basketball, not rec league tackle football. I guess I could see football being different as it relies on more coordinated plays.
In basketball, if a player attended practice the week before the game, they were guaranteed a minimum playing time. The coach was who indicated whether someone attended or not unless a parent complained. Most skills (dribbles, shots, passes, picks, etc.) could be practiced effectively with 1-3 people. I'd feel fine offering my kids a "makeup" practice as long as everyone got an opportunity to attend so I wasn't showing favoritism.
If a sport requires you and your XW to get along, seems you're out of luck until you repair that burned bridge. Maybe stick to the sports that don't require any cooperation until you're ready to tackle that?
