It more felt like Howson was asking for the moon and the whole shabang (sp?) and no GM was stupid enough to accept it. And there was talk about Howson acting like an idiot, talking to teams not confirming if they were on Nash's list or not.
So he was afraid to get lynched by the fans for messing up everything so he threw Nash under the bus as a distraction IMO.
Nash requested a trade. I don't see how it's throwing him under the bus to acknowledge that, I think the fans have a right to know if a player wants out of their organization
