I don't shoot at your level, but I struggle with the problem you have poised here. I would have thought given the high quality light in a pro arena that 1/500 would have stopped action though I note that ISO is "only" 1250. Yes at f/2.8 not everything will be in focus, but this pix has an oddity about it that I often encounter in much worse light and a slower pace. That is, things that should be crisp don't seem to be while other parts of the fame seem to be sharper. I'm looking carefully at 34 (nice expression BTW) and the only truly "right" part are the folds in his shorts. And the ball. Did the AF point land on the ball?
Both 34 and defender's left feet are showing blur. Wide aperture, I'd guess except I'm bothered by the fact that the rear green player's face is almost as sharp as your foreground. The two out of focus (motion blur?) left feet probably suck the eye to them detracting from the overall quality of the pix.
You are obviously a far better photog than I (I'm shooting dank high school gyms with rapidly cycling light), but if it was me I think I might kick the ISO up to 1600 (Don't know the limits of the D3s - I shoot with a 1DIII) and narrow aperture a bit - maybe 4.0 - and of course kick up the shutter speed. Worth an experiment.
One thing for sure, I'd kill to get this quality out of my 24-70 at this low of ISO. Actually a nice pix, but I sense the same irritation with it that you do. Oh, well, onward towards perfection.
