Webby, I think that IS exactly what their after
It depends on what the problem is with your long clearing, distance or accuracy?
You mention arc, this is probably one of the hardest passes for a goalie to make, as it is a touch pass where the weight of pass has to be exact to get the ball over a riding attacker/middie and to your breaking middie to him in stride while he is sprinting away from you.
The easiest way to improve is to do the drill in the video with middies breaking out from restrainer.
If you can't hit them, look at restringing your stick or changing your mechanics, so the stick moves through a perpendicular plain to the ground.
You don't have to bring your stick from behind your head as your not trying to deceive anyone, straight back and straight forward.
Perfect mechanics for goalies are the same as perfect mechanics for outfield players passing.
- turn side on to target
- point toe at target & butt-end of stick
- step toward target and follow through with stick
- finish with head of stick pointing at target
Most common error for goalies is that they have huge bucket of a pocket but don't have shooting strings set up to throw outlet passes, if your stick throws down, you need to adjust your shooters (loosen) until you can pass with it.
