This is also what I heard and it makes me very nervous regarding Bergman and Butters for the same reason.Quite amazing Ralph has framed it that way.
Houston first approached Ken before anyone else about wanting to go home (said approach happened mid last year). And Ken, thinking he controls everything, essentially promised Houston that he would be traded at the end of the season.
If Ken had kept his mouth shut and simply referred Dan to the list management team to discuss, Port would have had far more bargaining power at the trade table.
Ken didn't open his mouth out of selflessness - he did it out of stupidity and ignorance.
This guy would genuinely blow up this list before he left so that later it looks like his tenure was actually better than people gave credit for. He's extremely good at controlling the narrative around him regardless of how bad it is.
