Shouldn't there be an age limit for backhand looping?
Yesterday I coached one of our 7-year-olds for an hour. That in itself is rare - most at that age do only 30 minutes at a time. But this one was a bit ahead of the curve for the average kid in that age bracket. He loops just about everything on both sides. He regularly backhand loops 5-6 in a row against a block. And he can fish and lob with heavy topspin, often forcing me to miss smashes not because I couldn't handle the spin, but because I was having difficulty believing he was putting that much spin on the ball.
This is how the game is changing. There was a time when few kids would learn to loop before they were 9 or 10, and that would only be against backspin. Looping against topspin wouldn't start until even later. Now, with sponges that practically loop the ball for you, and with more and more full-time training centers with full-time coaches popping up around the country, the level of play is going up dramatically, and players fall behind if they wait until they are 9 or 10 to learn to do what others are doing earlier.
Many of the top sub-10-year-olds still mostly hit in matches, but the better ones are looping more and more in practice, and it's just a matter of time before they incorporate this into matches. It's scary watching a 10-year-old flawlessly backhand looping off the bounce over and over in drills, and knowing you will have to face that in matches.
