John McEnroe’s Forehand vs. The Modern Forehand

Below is a slow-motion video of John McEnroe hitting forehands. Despite the fact that McEnroe’s forehand looks very “old school,” he’s still got almost every fundamental necessary for hitting a modern forehand. Here’s a list of the requisite fundamentals –

• Pivot and Shoulder Turn
• Racket Back
• Swing to Contact
• Follow Through
• Continuous Swing Path

He’s missing one of them. Can you name which one? Post your answer in the comments! Also, ignore the fact that he’s using a continental grip.
