"You wonder how long Tiger's patience will last."

Mark Reason reasons that Tiger Woods is about to get tired of being humiliated by lousy driving and will switch teachers. I'm not sure I buy the humiliation angle just yet, since he's 0 for 1 post knee surgery in the majors.

This is an intriguing stat, though I'm curious how it was tabulated:

Woods has been with Haney now for five years and his driving remains something of a joke. In the six or so years that Woods spent with Butch Harmon he hit the fairway on average 68.66 per cent of the time. In the Haney era that average has dropped to 57.82 per cent.

In golfing terms a 1 per cent margin is colossal. It's the difference between 28th and 140th place on this year's driving accuracy table. There isn't even a relative increase in distance to compensate. If anything, Tiger is a shorter hitter relative to his rivals than he used to be.

Naturally, it should be noted that in the years since the Harmon era, fairways narrowed quite a bit in an effort to slow down drives (and boy that worked!).
