In cricket, a fielder is should never try to field using legs. One should dive if absolutely required but not try doing the football. This is basics.
But in a match that India went on to win, the indian skipper and bowler applauded Ashish Nehra for doing just that. When winning, the wrong looks quite ok and when loosing these things start to sting.
So it’s very important that one sticks to the basics and does the right thing. Afterall one never know when we get on the loosing side!
