Honestly, the Spurs not resigning Bowen is about as close an act of betrayal as there is, IMO (the Spurs had no reason to go in another direction, having ballsed all out with the RJ trade).. he isn't 2007 Bruce obviously, but the 2009 Bruce was underplayed and underrated now that we see Bogans attempting to take his place. Bowen's shooting is missed, especially. He could have still earned a niche on this squad as long as he shot 40% from 3.
As it is, the rest of our perimeter is too stacked offensively for an offensively inconsistent and good-but-not-incredible+undersized defender in Bogans.
