I think it's kind of silly for people who know next to nothing about an athlete to think they have any idea what is affecting their performance for better or worse, especially if they claim some sort of insight into the athlete's psychology and personality and motivations. That's especially the case here, where there's pretty strong evidence that contradicts the theory. Look how hard you had to work to account for his 2013 season (including ignoring the significant injury in 2014 that forced him to miss the Masters for the first time) in order to keep the silly theory alive, rather than just accept the fact that none of us have any idea what's wrong with him.
Of course we don't know. But message-board speculation is totally harmless, isn't it? Who cares if we don't know/can't know or whatever? Still interesting to talk about. Others' mileage may vary, of course.
Can't speak for others, but regarding his 2013:
isn't 2013 kind of fading into the rear-view mirror of Woods' career rather rapidly? I know, I know ... only two years ago. And he was injured in 2014. But still.
BTW ... injuries in 2014 kind of plays into my larger point anyhow.
Woods' career is -- right now and for most of the time since Nov 2009 -- sustaining lots of hits that are probably having a cumulative effect on his 2015 game. Some tiny hits, and some bigger ones. Hits that get plastered all over
Sportscenter, and hits the public will never know about. Surely we don't need to have inside knowledge to feel like the statement in red makes intuitive sense?
We're all human beings. As is Tiger Woods. Do we really have to be an athlete on his level to understand how he might be affected by a bunch of real-life stuff piling on? I don't think we do. Again, others' mileage may vary.
