Generally yes, you need to be tall. If you aren't tall you need to have excellent speed or jumping ability. However, just because you are tall doesn't mean you are good.
So in the end, it all comes down to skills. If a tall person and and a short person have the same skills and about the same athletic ability- taller does win out...
Yes some pro players are "short" If you consider 5'8 for girls and a little over 6'0 for guys... short. lol
