Seems pretty clear his body is done at this point.
No!?Yes. I do. 3-5 more
No. He doesn't know where the ball is going. His putting is not what it uses to be and there is a lot of talent on the PGA. He is no longer feared, and I don't think he is mentally the same guy he once was. Personally I wish he could come back to his former self because it would make for great theater specially with Mcilroy around. I am rooting for either Lefty or Ricki Fowler to win the PGA.
Yes. He's hurt. Needs time off to get healthy. One only needs to look what at Phil and Ernie did this week to realize players can still play in their 40's if healthy. It's not rocket science its golf. The difference between these guys is not that much. I do agree with one thing that Faldo said this week. The "Tiger era" is certainly over, but he is still good enough to compete when he is physically prepared.
