Chad, I know for the NHL they shoot in the 1/1000-1/1600 range to stop the fastest of the fastest. But, just a suggestion depending on the age and skill level of the players you are shooting, you might want to lower your shutter speed down so you don't have to push in post as much. I shoot 1/500, 2.8, 3200 and have no problem stopping motion, however, I only shoot 12 and under right now. But, even then I still have to push most of my images about 1/2 a stop. If I could shoot at 6400 or 12800 it would be great, but that will have to wait until I save enough pennies to buy the 1DX for next fall (or maybe the 5DIII if it is released and has good AF, decent FPS, and good low light ISO, which I'm skeptical of).
