Good action shots but maybe better in colour.....?
Not if the opponent is in a bright uniform.
I always HATE it when the opponent shows up in
BRIGHT RED 
At that point, shooting the game is reduced to practice, unless you can get shots without an opponent player in the image.
Nothing wrong with red, well okay maybe it is hard to shoot. But there was you a photo challenge to get a good clean shot. Test the camera and test the photog.
The team I cover, that my kids go to, is red and black. Last week, at home, they wore all red.
Get the exposure right in camera (or as close as possible) then if you must, use the HSL to pull back the saturation and luminance of the reds.
