It used to be every time I passed a golf game Tiger was always ahead, if not well ahead but lately he seems to be slowing down a bit. Did he just hit his stride or have the other golfers been catching up.
I think its the second item that you mentioned, other golfers are just catching up. He still got his touch and it will not fade any sooner. But we may expect someone is going to take his place sooner or later.
Tiger Woods has been going through a lot mentally since his father fell ill and later passed away. His father had always been there to encourage and support him, but after he died...it started to effect Tiger's playing.
