Yes, the 76ers' defensive rotations are in shambles right now. The defensive presence in the paint is nearly invisible. Stopping the fastbreak seems to happen only when the Sixers are taking the ball out of the net. The team is giving up the most points in the NBA, at 110 a game. They've given up 61 more three-pointers than they've made on the season. In a loss to New Orleans on Friday, the Sixers allowed the Pelicans to score 121 points on 55 percent shooting. Two days later in Detroit, they showed little resistance as the Pistons made 15 of their first 20 shots, including all six three-pointers. So what is the problem with coach Brett Brown's team as far as defending the basket? Believe it or not, much of it has to do with the offense. After getting a look at the roster he had been dealt last summer, Brown concluded that the best way for his players to compete would be to have them play an uptempo offense, filled with fastbreaks, leak-outs and long breakout passes. While that style seemed to work perfectly early in the season - with wins in the first three games - it has faltered of late, as the team has dropped eight of its last 10 games.
