Need help with creating a "spinning" effect....

Ok....I thought that this should be quite easy to create in PS (using PS6) but I can't quite figure it out. To be exact, what I want to do is create the effect of spinning motion (as in adding a bit of motion blur) on a basketball that has been positioned on someone's finger (the idea is to make it appear as if a youth basketball player is spinning a ball on his finger while not actually doing so). Motion blur doesn't quite work as it wants to make the ball appear as if it's moving in a plane parallel to it's position instead of spinning. Radial blur will make the ball appear as if it's spinning....just not in the correct direction. I would love some input on how to achieve this effect. I'll attach a pic of a basketball for anyone wanting to play around with it. Thanks

It's sometimes hard to think without having PS in front of you. First thought was to create couple more layers of a ball image and play with their filters/transparency and by moving one to the left a bit and another to the right. blur and distort the copies, to create illusion, that the ball is is snapped from sliiiightly different angle. Delet overlapping stuff, obviously. Just a thing to try, not sure, if it will work.

Do the Motion Blur, then Edit/Transform/Warp. Drag the top corners up and inward, drag the bottom corners down and outward. Use a good mask of the original ball to constrain the bluring and warping.
