He goofed. Sometimes life calls for a response of grace. This is one of those times. Grace to Steve. Grace to the winner. Grace to the runner-up. But do not water down the title for the winner by making the runner-up a co-winner.

He should never work in his field again. And be sued into bankruptcy.
