Tennis vs Soccer

I have coached soccer my entire adult life and can organize and arrange a practice for four to forty people in my sleep, but I am finding tennis to be a different animal entirely-- practice is much more chaotic and disorganized: there are challenge matches going on, and they end at various times; there are drills and fun games; there are balls EVERYWHERE; there's a court for our absolute beginners, who are just working on hitting the ball; plus, I try to work with some kids individually on particular shots . . . and there's no culminating scrimmage to end things-- practice start out organized but slowly fall apart as different matches and drills end at different times, so then you can end practice with whacky large group games like "around the world" and "lob doubles touch the net or fence" challenge and maybe some fitness . . . I really like coaching tennis so far, but I'm learning to go with the flow a bit and I can't wait for our first scrimmage to see the kids in action.
