The two most important comments that came from Tiger in his missed cut exit interview to me were.
1. He said he was disappointed he didn't win the tournament.
2. He said he prepared well but didn't prepare in cool damp conditions which was the difference.
Like an alcoholic , Tiger must admit and accept that he has a problem ( in this case , he's just not who he was and never will be, age wise, physically and mentally) until he does and finds comfort and peace with who he is now, he will continue with his up and down, mostly down battle. If he is able to accept who he is and what his game is now ( like a Furyk or Zach Johnson does) he might start consistently shooting some decent scores. JMHO
