Basket feeding too often or without context, can create a player who looks good at hitting a specific ball but struggles to develop the skills required to make the necessary adjustments to win matches. It would be similar to teaching someone to drive a car in a parking lot and expecting them to be able to navigate through New York City.
The nature of tennis can make unforced errors very tough to handle and bounce back from. In this exercise I have my players compete first using their own racket. If they make an unforced error they need to switch to the old racket, either a Jimmy Connors or Arthur Ashe one.
