first photo posting

late at night and against my better judgemnent this is my first photo posting here - I did do one on dpreview in my first couple of weeks of owning the d70 but was not ready for the 'feedback' - such a big site and I think people assumed I had more knowledge than I had.
I took this by mistake and only discovered the errant boot once downloaded - it had come off as he was running past.
I have had lots of trouble getting sharp sports photos and am usually disappointed with the many shots I take...nothing like more and more practice tho.
what do people generally use for action sports - manual or auto focus? i used auto with footy and manual for cricket but the majority (99%) are throwaways.
thanks for looking.cheers
