Some teams gaining separation in East We’re seeing some separation in the battle for the final few playoff spots in the Eastern Conference, and that’s not good for the Detroit Pistons. Washington is now five games ahead of the Pistons. Indiana, Milwaukee and Philadelphia are four games up on Detroit in the loss column. The Pistons, who entered the All-Star break ninth in the East, are one game behind Miami in the loss column. After Friday’s game against the Boston Celtics at Little Caesars Arena, their first following the break, the Pistons (28-29) play 15 of their final 24 games on the road, one of the biggest obstacles they’re facing. Who'll be in and out of the rotation? Q: I don’t get Stan Van Gundy’s rotation. Langston Galloway plays a couple of games and then inexplicably sits. Dwight Buycks shows some flashes as a scorer and then winds up in the doghouse. Why was Willie Reed playing in front of Eric Moreland and then all the sudden traded? It’s ridiculous that Henry Ellenson isn’t given a chance. What is their rotation going to look like when Reggie Jackson returns? – Dan A: Van Gundy’s rotation is dictated a lot by matchups, maybe too much. It reminds me of what Red Wings captain Henrik Zetterberg often said when former coach Mike Babcock was obsessed with line matching: Just roll the lines and let us play against whoever. Perhaps Van Gundy is over-coaching, like Babcock sometimes did. Van Gundy had no time frame on Jackson’s return from a sprained ankle, but he’s getting closer. We’ll probably know more this week when they return to practice Wednesday. Van Gundy said he’d like to go with a 10-man rotation. You’ll have Andre Drummond, Blake Griffin, Stanley Johnson, Reggie Bullock and Jackson starting. Moreland will be the backup center, Anthony Tolliver will back-up at power forward or center, James Ennis will sub at small forward and Ish Smith at the point. I think Luke Kennard will be first off the bench to spell Bullock, but I also think Langston Galloway will get minutes.
