James Harden has signed a 4-year, $228 million extension with the Houston Rockets, the biggest contract extension in the history of the NBA, according to a report by Adrian Wojnarowski and Brian Windhorst of ESPN.

Harden is eligible to make up to 35 percent of the Rockets' salary with the Designated Veteran Player Extension. Harden would be the first player to sign under the new DVPE rule. Russell Westbrook is also eligible for this for the Thunder.

Last summer, Harden signed a three-year contract extension through 2020 that was worth $118.1 million. Harden is slotted to earn $28.3 million next season.

Harden was the runner-up to last season's MVP award for the Rockets, thriving as a point guard in his first season under new head coach Mike D'Antoni. He averaged 29.1 points, 11.2 assists and 8.1 rebounds per game, leading the Rockets to a 55-27 record, good for the third seed in the Western Conference. Houston was eliminated in the conference semifinals by the Spurs in six games.

The off-season has already been productive for Houston, trading for Chris Paul from the Clippers. The Rockets are reportedly still in the market for another star, potentially Carmelo Anthony.

The Rockets couldn't be happier with what they have gotten out of Harden since trading for him back in 2012. Developing into an MVP-caliber player and getting the Rockets as far as the conference finals are the highlights. Hoping for more, this new deal and the addition of a player like Paul makes the future look bright.
