Use Continuous Shooting

I still can't get myself to hold that shutter release button down and just fire away when the action is occurring on the field.  Maybe subconsciously I think about all of those photos I'll have to review just to find the one that pops (like the one above).  But why have the capability of shooting at 8 frames per second, if you don't use it (My Nikon D300 with the vertical grip attached shoots at 8 fps).
