Kevin Durant decided his best chance for “growth” means leaving his beloved Oklahoma City behind for a big move out West to join the star-studded, record-setting Golden State Warriors and play alongside Splash Brothers Stephen Curry and Klay Thompson.

In the most anticipated move of the NBA offseason, Durant announced his decision Monday on The Players’ Tribune. His contract is for $54 million over two years and includes a player option, a person with knowledge of the deal said Monday, speaking on condition of anonymity because details weren’t made public. Durant’s move will become official as soon as Thursday, when free agents can sign their new contracts.

Independence Day, indeed.

“The primary mandate I had for myself in making this decision was to have it based on the potential for my growth as a player — as that has always steered me in the right direction,” Durant said in the article.

“But I am also at a point in my life where it is of equal importance to find an opportunity that encourages my evolution as a man: moving out of my comfort zone to a new city and community which offers the greatest potential for my contribution and personal growth. With this in mind, I have decided that I am going to join the Golden State Warriors.”

And the 2015 champion Warriors, who squandered a 3-1 NBA Finals lead to lose to LeBron James and the Cavaliers last month, know how tough Durant is in any lineup: They rallied from down 3-1 to beat Durant and the Thunder in a seven-game Western Conference Finals.

Golden State applied a full-court press to land Durant. On Friday in the Hamptons, the Warriors sent owner Joe Lacob, general manager Bob Myers, coach of the year Steve Kerr, Curry and Thompson to meet with the 6-foot-9 superstar.

Also Monday, the Warriors reached a one-year agreement with unrestricted free agent center Zaza Pachulia, a person with knowledge of the negotiations said. He spent last season with Dallas, averaging 8.6 points, 9.4 rebounds and 1.7 assists.

Durant, the 2014 MVP and four-time scoring champion, led the Thunder to the NBA Finals in 2012 and to the Western Conference finals in four of the past six years — and he’s only 27. He recovered from a broken bone in his right foot that cost him much of last season to post one of the best years of his career.

Durant met with the Thunder, Warriors, Los Angeles Clippers, Boston Celtics, San Antonio Spurs and Miami Heat once teams could begin negotiating with free agents.

With the addition of Durant, the Warriors become the league’s latest team to add a superstar chasing a championship to a lineup of All-Stars.

James made the move from Cleveland to Miami in 2010, joining a lineup that featured Dwyane Wade and Chris Bosh. They reached four NBA Finals as a group and won two championships.

“I’m from Washington, D.C. originally, but Oklahoma City truly raised me. It taught me so much about family as well as what it means to be a man,” Durant said.

“There are no words to express what the organization and the community mean to me, and what they will represent in my life and in my heart forever. The memories and friendships are something that go far beyond the game. Those invaluable relationships are what made this deliberation so challenging.

“It really pains me to know that I will disappoint so many people with this choice, but I believe I am doing what I feel is the right thing at this point in my life and my playing career.”

He should be a good fit in Golden State’s varying lineups and gives All-Star Draymond Green another physical body and rebounding presence to complement 3-point aces Curry and Thompson.

The Warriors topped the 1995-96 Chicago Bulls’ mark and set the NBA regular-season wins record with 73 victories and led the league in scoring.

Durant has been a difficult opponent for the Warriors __ he averaged 30 points per game against them in this year’s Western Conference finals and dropped a career-high 54 points on them in 2014.
