Pickleball and Paddleball many years ago, were invented for people, and there are millions of them, who never had the lightbulb go on in their heads, no matter how much they played, about the proper way to hold a tennis racquet, serve a tennis ball, and just basically control the racquet face. Tennis is still king and always will be, and pickleball will grow but I see it eventually going the way that Paddleball and Paddleball courts did back in the 1980’s. Tennis and Golf are very similar in that hitting with power AND accuracy are so dependent on controlling the club face or racquet face.
