People who make their livelihood on the back of a sport don't really have any incentive to not be overly dramatic during the big game. Any promoter will want people's eyes on the game. Controversy does that. Carlson's draw offer did that, and so did all the criticism of it.

Not that I'm being cynical about it... nobody wants to be a champion that nobody remembers. Especially not in an age where computers consistently outplay humans.
