Beach for the indoor player

A little interview I found online:
While many Sacramento area players report their coach has discouraged or banned
them from beach volleyball you have embraced the program.  What would you say to
Sacramento coaches who believe their players should not play beach?
Anytime you touch a volleyball is good.  If you can also play in a competitive or fun game that
is a bonus.  Time on task!  The more you play the better you will be.  Beach turns players into
all-around players.  Indoor may be getting more isolated but an all-around player will make
more points for a team than one-dimensional players.
A little interview I found of a Sacramento Club coach from Pepperdine and the national team:

How do you reconcile attitude of these coaches with the widely published beliefs of
Misty May, Kerri Walsh, Karch Kiraly and others?
The will to win by these players you have listed is enormous.  Most of the best beach players
had great indoor careers.  The crossover is huge in terms of the mental aspect.  I truly believe
that beach volleyball is a much tougher sport to play with all of the elements.  This can only
make you a better indoor player.
What can parents expect from their children’s participation in beach volleyball?
I think parents will be overwhelmed at how much confidence and self-esteem is established
from playing Beach.  There is something really pure about doubles on the sand that you do not
find on the indoor courts.
