I don't think one should read being mentioned in trades as a sign of disdain or displeasure with a player. i think the reason he gets mentioned so much in trade scenarios here is because he would likely be desired by other teams.
PGs are hard to come by and if throwing Beno into a trade that would take a bad contract off the spurs books, then that's something I'm sure the front office would consider. But i'm also pretty sure they'd prefer to keep Beno around.
