@ossobuco,
"why do men cheat" would be a good thread subject, but "why did Tiger blow up his marriage and probably his brand" is not. He has been around but no one knows him, and he is not talking. We don't know the wife either, and she is also not talking.
At the relaunch we will see Tiger giving a version of why he did it, but we also will know that it is likely that what he says comes off of a script put together by consultants.....because that is how he has rolled all of his life.
