I think the USGA has gotten away from what made their major championship great. It's all about countering distance now, and not by narrowing fairways and pinching doglegs and growing rough, but making holes dramatically longer to counter the longest hitters.
It has significantly reduced the art of shotmaking.
Outside of Bubba Watson, I don't know of a long-hitting player today who has the remote ability to carve the ball on-command like he can. Unfortunately for Bubba - putting is also part of the equation and hasn't exactly been his strongest suit.
The test required years ago in this major has changed dramatically during the bomb-and-gouge era. It's not the same tournament anymore.
