I read some of the stuff Brooks said, and he doesn't seem to be really gung ho. So I can understand Azinger and others who are critical of these comments. Most players would LOVE to play in even a single Ryder Cup, and are rabidly enthusiastic about the matches if selected.
On the other hand, he's pretty honest, the formats and requirements ARE way different from any individual player's normal procedures. The best players have fine-tuned their schedules, both on and off the course, so It HAS to be an adjustment to follow a schedule set by someone else. And yes, having played a bunch of fourball match play, and at least some foursome match play (the Newport Cups are an example), they require a change in mental approach as compared to individual stroke play. To me, if you're going to adjust successfully to this stuff, its critical to recognize the ways in which you'll need to adjust.
