I think with sports it is particually valid. The camera I have shoots 3.9 fps, which is slow and I use that to my advantage. I hate having to go through 600 images after a football game. I started a project on a construction site the other day for my documentary photography class. I took three cameras, two with motor drives and one without. I had planned on not using the motor drives. That didn't happen. I did use them because they are nice to have under those conditions. However, I used the single shot mode.
