SwingVision - Briny Baird Iron

I found some SwingVision pics of Briny Baird hitting an iron off the tee. He doesn't possess the greatest of swings, but these images illustrate how irons should be swung with the club approaching the ball on a slightly descending path. Notice that the hands are ahead of the ball with a bowed and supinated left wrist at impact and that the club strikes the ground after impact with the ball. These are fundamental concepts for proper ball striking.
