The problem I have with this, and apparently others do as well is IF Tiger thought he saw the ball oscillate, of course he stopped moving things further to prevent it from then moving. I don't see why this is a difficult concept. Its been said a bunch of times but it seems to bear repeating that it's easy to see the movement in HD, slow motion, and from the angle recorded. What would it look like from above? I can't say as I wasn't there. If this is anyone but Tiger, and they said they thought the ball oscillated, people would not be making such a big deal. He took a 2 stroke penalty, what more do you want?
