What I like about it is, in servo, the ability to lock down the focus. With the focus dancing all over in servo, there is no way to recompose without the focus refocusing as well. That drives me nuts.
I shoot now with one shot, half click then recompose, and with servo, its just shoot and crop to recompose, or just shoot and hope the servo focuses properly on the single center spot.
I hear you though, I read somewhere that 10% of pros use it, so thats a small margin but, I would imagine that 10% of photographers or less primary do sports.
I am just rambling at this point about things I know nothing about

, but I
really like the idea of back button focus and stopping/locking the servo focus.
I don't worry so much about locking and recomposing. For a sport like basketball, I keep the shutter button half-pressed and follow the action. I have the focus points set to inner 9 and I just move them around if I see that something will need recomposing. It takes a little practice but I know exactly what direction to move the wheel to get the points I need, whether I'm in portrait or landscape.
