No question Bonner has disappeared against the Mavs and the Lakers. Offensively, there is no excuse. Defensively, he simply has no chance at adequately defending Nowitzki, Gasol and Odom.
It never matters to this coach, though, who apparently thinks it's fun to play him plenty against those teams and watch as those players destroy him.
Short of it being a no-brainer type trade, I wouldn't trade Hill. He's a good fit on this team. Blair, on the other hand, isn't. I wouldn't shop Blair per se, but if this team could acquire a better fit up front, I'd be open to trading him.
Blair is a terrible match-up against the Lakers and the Mavs. Unfortunately, they're the best and (probably) the third best teams in the conference. If this team has designs on going far in the playoffs, they'll have to go through at least one of, if not both of them.
This season, it's simple, come the playoffs, he can be the fifth big. What about next season, though, when McDyess is retired? Since this coach refuses to play Duncan and Splitter together, is a PF combination of Blair and Bonner supposed to suffice against the Lakers and the Mavs? Because it has no chance to.
