I reckon that your camera has reduced its exposure level to a mid-gray which is how it does all its metering. As a result the ice is grey and it's all a bit underexposed. So when shooting something that has lots of white (skiing is the same), you need to over-expose to get a nice-looking shot. You can do this by dialling in some exposure compensation, or use manual mode.
Secondly, judging from your depth of field which is quite "deep" or "long" i.e. lots of the scene is in focus, I'd guess that you aren't using a very fast lens. You're probably at f/5.6 or suchlike. As a result, you cant get much light into the lens as the hole is quite small, so your shutter speed wont get high enough to really freeze the action.
The good news is that you can fix this. The bad news is that it will cost you ££££s! You're after a wide-aperture lens at least f/2.8, and that means large lumps of precision-ground glass which will cost a lot. The larger aperture will mean you can get more light in so have a faster shutter speed. It also has the desirable effect of reducing your depth of field, making stuff in the background blurry and making your subject (the players) pop out from the background.
Lastly, positioning. For this sort of stuff the pics look much better the lower you can get.
