I think he's a threat, not for the title, but to be a severe spanner in the works.
IMO at 41, he has lost the killer/winning edge he had, but has not lost the burning desire to win at all costs...... so if he sees the opportunity to become a mobile roadblock, or bend the rules to suit him, then I'm sure he'll grasp it.
I would love to be proved wrong on and see him lift another title though, would be absolutely epic!! What sort of odds is he getting at the moment??
Cheers,
Grant
