Well, you're gonna think it's an issue, then, because this is certainly not the last time you're going to see this type of decision.
To me, they are very very different in strategy. The shots are very very different. The only real similarity is not going for the hole, instead pretty much deciding on the tee you're playing for a par, not a birdie chance. In that sense, there are more similar holes than different holes at Oakmont. Heck, you could make an argument that this type of decision exists on almost every hole at Oakmont.
I used to hate the notion of protecting par. After spending so much time at Oakmont in 2003, then watching the Open at Shinney in '04, I have a whole new appreciation for it. I think it encourages thoughtful golf more than just about anything else.
But that's obviously just my opinion, others are entitled to theirs.
