Of course not! (unless there's a sh#tload of money involved of course)
I would even think twice before I'd share the ring with someone like Audley, although he'd probably be more scared in there as I would be.
But that doesn't mean "Haye trashing" is completely out of order here.
Example: If a tennis player has a big mouth saying he'll win Wimbledon and whoop every player doing it, has a very tight 5 setter against the first reasonable player he faces, and gets eliminated against the first really good one afterwards blaming some minor injury for his loss, will anyone just have to be quiet because he'll beat almost all of us with 3 times 6-0?!?
I don't think so... certainly if that same player runs his mouth again when next year's Wimbledon comes along.
