So.....that was a nicely thought out apparently....Let's see how the US Open/PGA comment plays out over the next couple years....
For the next round - I still think Rory will find his old game and get the C-slam, but as for even more majors for Tiger...now that he's playing like he should, Tiger gets 4 tries a year, Rory just the one.
I would flip this around.
Most tour-level players can't and shouldn't teach after they are no longer competitive. They have no knowledge or skill in teaching, nor any talent to teach, let alone teach golf.
But it's an incorrect and damaging one that should vanish from usage. I think we'd all agree that golf, and the world at large, can use more smart, dedicated, trained, and fairly compensated teachers.
