OK, so there's this show on the Tennis Channel called Tactical Tennis. It features Paul Annacone providing analysis while two club level players hit behind him. I would guess the players are 4.5 - 5.0 level. Their strokes look like something you might see on your local courts. Anyway, the amazing thing is a couple of times Annacone gets on court and demonstrates the right way to do things, or the drill. What is truly amazing is to watch him hit with a 4.5. - 5.0 player. The NTRP player is swinging his/her ass off and Annacone is generating twice the pace and really good placement with half the swing. Average Joe versus World Class Pro.... It ain't a contest.
