Question for Jena!!

or anyone else that wants to answer...I've been working at a volleyball camp this week and i overheard some coaches talking about the correct technique to passing. They said that you should not pass with your fingers out, like in this first picture, but they should be tucked in like this second picture.

Now...i was taught to pass with my hands in this first picture position. Have THEY (whoever THEY are) changed the way you should pass? Am I all of the sudden outdated?) HELP!!!!

Jena, what have you been teaching your girls!?!?!
