Do you think volleyball is an easy sport?

No. Its not true. There is no game which is easy. 

No, not when you're playing at a competetive level rather than recreational.

Volleyball is like the recorder--easy to play but hard to play well.  They teach it in schools because almost any group of kids can keep the ball going back and forth.  But if you get into it and learn the tricks, it's a whole different game.

Yes and no. I think it's easy with respect to novices and non-athletes being able to, with relatively little practice, play competently enough to have fun and not feel embarrassed by failing to at least keep the ball in play and dragging your team down. I have almost no athletic ability, yet I'm a decent volleyball player. It's the one sport I'm likely to be picked first for instead of last. But playing volleyball competitively, like collegiate or pro, for example, that's not easy. 

I suck at volleyball, but i'm 6'7" so i'm better than 95% of the population.
