I'm not sure if there is something to it but too me it looks like pros almost never miss a ball into the net. they will hit one long and especially miss the sideline but very rarely even hit the net cord, let alone the net. on the other hand those very good college players: http://www.youtube.com/watch?v=H-EHF9jLXTM seem to miss quite a few balls into the net, especially when they go for winners (especially the red haired guy in the video). on the other hand with the pros you see that much less: http://www.youtube.com/watch?v=NC2qcfnTP-g Of course I understand that pros are more precise in general and tend to make less overall errors but I think even if you normalize for the same errors pros will miss less in the net. why is that? does it have to do with better footwork and balance?
