Definitely a hit or miss process. Glad I wasn't using real film!
I found it tough to keep on track with the movement and not drop the camera as I panned, or rush or lag.
Monopod or tripod with pan head would probably help. These were all handheld.
Had a lot of background 'stuff' to avoid such as bleachers, sheds, scoreboards, etc.
(I photoshopped out a shed in one of these pictures - you can probably figure out where)
Best shutter speeds were in the 1/4 to 1/8 second.
Longer exposure left me without any subject, shorter exposures looked like oops shots.
Bright sunny day - don't know how clouds or artificial lights may affect best choice of shutter speed.
I've tried some motion blurs in Photoshop before, but there's definitely a difference between doing it in-camera vs. in-computer.
