According to Chris Forsberg of ESPN Boston (via Hoops Rumors), the Pistons traded Will Bynum to the Celtics for reserve C Joel Anthony on Friday. The deal doesn't come as a huge surprise, as Bynum had found himself on the outside looking in after the Pistons signed D.J. Augustin and drafted Spencer Dinwiddie over the summer. Bynum was never going to fit in Stan Van Gundy's designs due to his lack of shooting ability, something that SVG covets in his PGs. Any minutes Bynum figured to receive this season should easily be absorbed by Brandon Jennings, Augustin and Dinwiddie.
The Pistons acquired Anthony in order to bolster a frontcourt short on size after it was announced that Aaron Gray was suffering from a heart condition that may prevent him from playing this season. With Gray sidelined, the Pistons options at C were confined to Andre Drummond and Greg Monroe. With Monroe also slated to play a good amount of minutes at PF, any instance of foul trouble or injury for Monroe or Drummond would leave the Pistons with no depth at C. The Pistons had added Hasheem Thabeet to their camp roster, but he has only played five minutes this preseason, indicating that he hasn't given the coaching staff any reason to believe in him. Detroit picked up Anthony to provide an insurance policy on Monroe and Drummond, something that they thought they had in Gray.
As far as what he brings on the court, Anthony doesn't have much to offer to the Pistons. If you combine the best per-36 numbers Anthony has managed in his career into one stat line, you still only end up with a guy who's capable of 6.1 points, 7.4 rebounds and 3.2 blocks. As you can see, Anthony does little from a scoring standpoint and isn't much of a rebounder. He may offer some form of rim protection, but Anthony's best years appear to be behind him in that regard. Anthony's best years as a shot blocker came between 2008 and 2010. Whatever he does or doesn't offer on the court shouldn't affect the Pistons season much; if they're counting on Anthony to produce, something has gone horribly wrong with Monroe and/or Drummond. On a normal day, Anthony is six fouls and a guy holding down a spot at the end of the bench.
