For many NBA players, their desire to get better fades away after receiving their first large contract.  However, that's not the case for Brooklyn Nets guard Spencer Dinwiddie.

Spencer Dinwiddie agreed to a three-year, $34.5 million extension with the Nets on December 13th. The contract had a player-option in it as well. This deal was Dinwiddie's first large contract extension, something that he truly deserved.

But instead of being satisfied with his current performance, Kenny Atkinson said Dinwiddie isn't happy with his success so far and admitted that the 25-year-old is looking to get better as he has throughout his entire career.

Dinwiddie comes off the bench for the Nets and has been a very consistent and efficient scorer.  While he doesn't need the ball as much to be successful, he still leads the second unit with 16.9 points, 2.5 rebounds and 4.9 assists per game.

The 25-year-old is shooting 47.4 percent from the field, 36.8 percent from deep and 77.3 percent from the free throw line.

The Nets are 11-18 on the season, ranking 11th in the Eastern Conference. They've played surprisingly well for a team that hasn't had a first-round draft pick in four years now.

Brooklyn acquired veteran post-scorer Kenneth Faried this offseason, and along with Dinwiddie, Caris Lavert and D'Angelo Russell, the Nets have had the 15th best offensive rating this season.
