Yep, maybe as I get further up the learning curve I'll have better control over choosing selective focus points, but right now, I tend to watch the subject, waiting for the play to develop, work on framing tight without amputating limbs.
I tried a non-center focus point (higher... e.g., helmet level in vertical orientation), but I got frustrated when the ball-carrier would dive or get tackled... the subject went low but my focus point stayed high.
But for slower moving subjects, like speakers at a podium or a portrait, sure I adjust to a specific focus point.
