I cannot stress this enough to divers and coaches. You CANNOT get a great score on a dive without a great entry!
I know what the rule book says. I know what they tell you in judging clinics -- BUT it is nearly impossible to get a great score on a dive that does not have a great entry. Cheating? No! Biased? Maybe. Incorrect? Perhaps. But if you watch enough diving at meets or on television you come to understand that a dive with a great entry is looked upon very favorably by the judges. A great entry actually seems to camouflage some deficiencies in the dive. Right or wrong it is reality so you as coaches must learn how to "play the game."
What Does This Mean?
It means that you as coaches should take the time necessary to teach your divers how to get into the water with little or no splash. Make sure they know how to grab a flathand, line up and lock out on every dive. It makes no sense to teach your diver more difficult dives if they cannot do their current dives vertically, with good form and a AT LEAST a good entry. A good dive with a good entry will get a good score but in most cases you will find that you cannot get a GREAT score without a GREAT ENTRY!
Now get back to the pool and have your divers do some more lineups (both forward and backward) to perfect this most important of skills!
