I know that bb+other instructors get mad over the way oscar claims his way is right + the more conventional methods are wrong. He does come on pretty strong, so i can understand him ******* off many teachers. However i am just a player wanting to get better at this game.I could care less who came out with this or that method first.Or who claims to have taught more modern methods first.That does not mean anything to me. I do know that oscar wegners teaching methods were different than the lessons i received from usta instructors.About 6 years ago i decided to get serious with tennis, i used to just rally around with the wife once in a while. Both of us took lessons+ i researched different video lessons+ decided to purchase oscars play like the pros.That is when i discovered his methods were much easier to learn. I was being taught by instructors to take the racquet back early,keep a closed stance, follow through towards the net.Then oscar was saying the complete opposite,open stance, keep the racquet in front until ready to swing, follow through up+ across the ball. There was no comparison in the 2 different teaching methods. I learned so much faster with oscars videos.When he said think of brushing the ball not hitting it, that made a huge difference. I was now hitting topspin so i could take big cuts at the ball+ still keep it in the court. After that i really started working on racquet head speed+ kept getting more+more topspin.I was taking a lesson after that with a usta instructor + he asked me why i was trying to put so much topspin on the ball.He said just the natural stroke of going from low to high will give you enough. I would try his method but i would hit to many balls long.So i went back to the exaggerated topspin which enables me to swing out with much room for error. At the tennis club i play at anytime i play someone new the first question they ask is how do i get all that topspin.These guys have been playing for years, way longer than i have.Most use eastern forehands with conventional methods.Most also have no idea how to handle that heavy kicking topspin forehand. Not to say that their method is no good, many of these guys are really good.But i think it is much more difficult to become consistent with that style. I really think that the way oscar teaches is different+ easier to learn than a lot of the conventional ways.But if you really want to know try it then see what you think.
