Why not? IS won't stop subject movement, and if you're shooting with a high enough shutter speed to freeze a football player (or whatever), camera shake shouldn't be an issue.
That's a good point.
I don't shoot much sports, but I do shoot moving subjects, like birds, airplanes, kids running around, etc., and the stabilized lenses seem to help with most cases. But, I guess at higher shutter speeds IS wouldn't be needed all that much. But, it does come into play if the OP wants to shoot wildlife that's not moving around that much, like ducks in a pond, zoo animals, etc.. Plus it helps for shooting portraits and such without needing to rely on a tripod or monopod. Which is helpful when you're out in the field and are just doing casual shooting. I know there's been plenty of times that I would prefer either not to carry the tripod around, or I just don't want to take the time to set up. Impromptu shots are easier when they're impromptu.
