I have a 70-200mm f/2.8 Sigma, no VR/IS/VC; use it for sports a lot. I shoot JPG (sports only to get max pictures) at maximum burst hand held. I can move quickly and follow the athletes and it's only me who causes blur. I have a Canon lens with IS and when I've used it for sports I seem to get more throw-aways due to blur. I think the IS actually tries to stabilize the movement when I'm following an athlete (and maybe over compensates).
I do appreciate the IS/VR when hand holding and trying to shoot birds at the feeder or other nature/landscape shots.

Try using Mode 2 on the IS for your Canon lens. It will allow you to track the action horizonatlly.
