If in tennis, somebody was deemed "too small" to develop power, I would understand. But they say "too short" which doesn't make sense to me. A 5'10'' tall, 210 lbs guy should, given good technique, hit harder than a 6'2 tall 180lbs guy.
In serving, I agree that height matters a whole lot. But for power of the ground it really shouldn't.
You don't seem to know how to hit a tennis ball efficiently. Stocky guys generally can not hit tennis balls nearly as hard a long flexible guys. You can't throw a brick as fast as you can crack a whip (cracking the whip is when the tip goes supersonic).
Some day there will be a short guy who becomes #1 again. From the early days of tennis most of the top guys have been 6' to 6' 3". There have always been exceptions to that rule - guys who beat all the taller guys. There will be again. It is a disadvantage to be shorter than 6', but not one that can't be overcome if the shorter player is the better player.
