That's pretty well it except I'm not sure you want it to be on continuous focus. For sports, unless the subjects are all at infinity focus, you have too little control over what's in and out of focus that way. I would suggest experimenting with manual focus and try to avoid continuous auto-focus.
Even with dSLR's it's easy to "fool" the autofocus when you are set-up to shoot a particular subject or subjects and a player runs in front of the frame. With manual or instant focus you have a better chance of avoiding this problem.
