Very timely and great post.
Yesterday, Cliffie said that DP gets extra power on the forehand because he uses a more open face compared to other players. I wanted to be the first to start a DP thread, but you beat me to it.
We want players with diverse styles - everyone playing high-percentage tennis gets boring. Tennis is not like an auto plant where you want everyone working predictably so that your car comes out reliable. There can be only one champion in a tournament, whatever style of tennis is played, and nothing is "on the line" for the viewers.
