Is it the way he talks to his ball? Are you a fellow talker ?
I actually hope you are right. It is not enjoyable watching someone deteriorate in the way that he has. Do you think it is a technical issue or mental.
No expert but has to be both I think. Everyone said his technique wasn't perfect, which was part of his charm, and once that went a bit and he stopped holing about 200ft of putts then the mind must start playing up. Find him fascinating - that last round at Birkdale he was absolutely shot to pieces and then he did what he did.
And no, I don't talk much to my ball other than cries of anguish and forgiveness..
