I have actually seen that happen on a recording I either have
or have seen, I'm not positive which. In the scene I'm thinking
of, this guy climbs up the wall, catches a pelota and returns
it from between his legs while still in the air. Yeah. I know.
You can actually see it done and still doubt.
On the business of holding on to the ball after a catch, players nowdays, catch the ball, go out for dinner (3 course), call their moms, their GFs and their therapists, take in a movie, then go back to the fronton and return the ball....after running halfway to the front wall.
