As a coach for youth players you see many strange things happen on court. Bad descisions in when to do what and so on, crazy shoots, strange reactions and sometimes you think what the ****just happened, what did she/he think when he/she decided to do that!?
But as they mature and learn more about the game and themselves "strange" things happening on court happens less and less. It will never go away totally and sometimes at least I forget that crazy things happen even on the highest levels just not so often.
Found this great video on youtube, enjoy even the ones on highest level screw up in so many ways and we should never forget that :-)
