5. Josh Green

Just a few days before the Dallas Mavericks' season began, they extended Josh Green's contract. Green was set to become a restricted free agent after this season, but Nico Harrison and company decided to give him a three-year, $41 million extension.

This seemed like a great decision at the time and still does, but Green has not taken the fourth-year jump that many people expected him to make. This season for the Mavs, Green is averaging 8.5 points, 3.2 rebounds, 2.3 assists, and 0.8 steals per game while shooting 49.3 percent from the field and 40.1 percent from downtown.

Green has had a very similar year to last season and was recently sent to the bench in favor of Derrick Jones Jr. Green's shooting, especially from the corners, has been excellent, but his defense hasn't been great this season.

While Green has the energy and athleticism to effectively full-court press, his defense in the half-court has not been great. Green struggles to battle through screens and looks lost sometimes. He has all the tools to be an elite defender in the NBA, it just hasn't happened yet.

Green still has plenty of time to continue to improve and it looks like he'll be a valuable role player for the Mavs for years to come, but he has not been as good this season as originally expected.
