Mark Cuban believes the improved depth of the Mavericks will make them a title contender.

"Our second unit really couldn't win games for us last year," Cuban said. "If you look at teams like San Antonio and Phoenix, their second units won games. We're going to be deep at all positions. People say, well, what difference is the ninth or 10th man on the team?

"Depth matters, and it's going to be a big difference for us. You're going to see us put pressure on teams early because we have depth. We'll have a much stronger second unit. In the playoffs, who beat us? It was George Hill. It wasn't Tony Parker."
