Once again, there will be major turnover among NBA head coaches after the 2012-13 season. The jury is out in Cleveland, where the Cavaliers are once again limping toward the finish line. They have a chance to do something no other Cavs' team has ever done: Finish last in their division for three consecutive years. Coach Byron Scott's critics are becoming more vocal as the season wears on. It was once viewed that his return next season was almost a lock. After all, the Cavs picked up the option year on his contract next year worth an estimated $4.5 million. What if the Cavs close the season on an 18-game losing streak? They've already lost seven in a row, as well as 11 of their last 13, heading into Sunday's game in New Orleans. Much of that carnage can be traced to the injuries to their top three players. But the problems might be deeper than that. The defense is one of the worst in the NBA. It struggles on some nights, and it is non-existent on others. That's a major concern to Cavs majority owner Dan Gilbert, and ultimately a hunch Scott could be on shaky ground. Scott's offense is largely ineffective. Often times, he hands the ball to Kyrie Irving in crunch time and asks him to make something happen. Break down your man, penetrate into the key and take a shot. Without him, there's nowhere to turn. Shaun Livingston, who now has the ball with the game on the line, doesn't have Irving's kind of ability. That leaves the offense in the lurch. For the most part, Scott is able to get the players to play hard. Right now, there is not enough legitimate talent, which isn't the coach's fault. He took exception to a question that was asked on Friday whether the players had quit.
