I own the 135 f/2 DC, and it's an amazing portrait lens. However I would agree that it has too many shortcomings to make a great action sports lens. The AF isn't terribly slow, but it has nothing on the lighting fast 200 f/2. What a amazing piece of glass that 200 is. (sigh, drool, want...).
My friend has the Canon 135. The Canon lens has a much closer MFD. I find that I have a hard time composing some headshots, especially when shooting DX, with the Nikon lens. It would be nice to get in a little closer at times. It's less of an issue when using the D3S.
