Watching a video yesterday the changing rules of basketball, quite a lot of today's players would be lost having to play without travelling, palming, turning the ball over, double dribbling, etc. And image today's baseball players with the 14" high-tech gloves having to try and field with the old mitts. And can you see anyone today doing a Wilt Chamberlain and playing every minute of every game of the year except for TWO minutes? Or imagine Ruth's natural talents enhanced by today's scientific training, etc.
