3fps just isn't enough for fast moving things, a lot of the time. That's all. As long as you have nice lenses, though, the AF is more than adequate for just about anything.
Maybe i'm missing somthing, but I don't understand all this hoopla about FPS. I rarely shoot machine gun sequences, I time out my photos, and get the look I want. I find that, no matter how fast your camera is, a lot of the time you are still going to miss the shot you want, but you'll get it a split second before, and a split second after.
So, FPS aside, what else makes the 5D a poor choice for sports?
