I gave it a 5 and I see lots of others did as well. I believe its because in this challenge folks were looking for action shots, but of course it didn't fit in with sports without players either ;-)
For me the girl in the front whose eyes look half closed was a real distraction. Might have done better had they all been looking at the hands as if they were getting ready to break and go into the game. I've learned here at DPC you gotta be really careful about stuff like that. Course it hasn't stopped me from entereing such things.
No real action, some motion blur in hands and faces, blown highlights, distracting background - must be the camera, why the background is not OOF at f/2.7
I think your entry is engaging and shows some great faces, but it shows more the 'after the game' rather than the action of the game. For that, I think it was voted low.
