As the Oct. 30 opener against the Washington Wizards inches closer Pistons coach Maurice Cheeks is revealing more of his thoughts about the playing rotation. After Wednesday’s practice he was asked if he could play five guards as part of the rotation and he was pretty definitive. “You can’t” Cheeks said. “How can you do it? I don’t think you can do it. It wouldn’t be fair to the guys that are playing. “You’ve got to say somebody’s going to play and somebody’s not going to play.” So that means someone among the group of Brandon Jennings Chauncey Billups Rodney Stuckey Kentavious Caldwell-Pope and Will Bynum will be on the outside looking in when it comes to playing time. Scratch that. The Pistons didn’t trade for Jennings and guarantee him $24 million over the next three seasons for him to sit the bench. So let’s look at the other four. Billups got the first chance at starting in the backcourt in Tuesday’s 91-69 exhibition victory over Maccabi Haifa and Cheeks has said Stuckey likely will get a chance to start in the exhibition season. You can assume that means they are in the rotation. That leaves Bynum and Caldwell-Pope. You would think Caldwell-Pope has the edge because rangy athletic shooters have been a major matchup problem for the Pistons in recent years and Caldwell-Pope was drafted to address that. Jennings Stuckey and Billups can run an offense so the need for Bynum might not be dire. But it’s a long season and rotations can change quickly. Cheeks said he communicates to players when they aren’t going to play so they’re not in the dark. “I don’t want to be sitting on the bench wondering if I’m going in the game” Cheeks said of players. “I don’t think it’s fair to the guyand he needs to get more work when he’s not playing so when the time does come he’s ready.”
