I would put the Detroit Pistons’ 123-111 loss on Sunday to the Philadelphia 76ers to be the most dispiriting game of the season. The Pistons looked awful and the game was boring in every moment that Detroit’s defense wasn’t so bad it made you physically cringe. How could it get worse? Well, tonight, the Pistons play the Sixers again. They play them at the Wells Fargo Center in Philly. The Sixers might have star center Joel Embiid back. And the Pistons will be missing Jalen Duren again, and might also be missing Bojan Bogdanovic, who scored 20 points and dished five assists in that first game.
