The most unpredictable NBA summer ever continued Thursday night when the Oklahoma City Thunder agreed to trade Russell Westbrook to the Houston Rockets in exchange for Chris Paul and a bevy of first-round picks, league sources told ESPN's Adrian Wojnarowski.

In Houston, Westbrook will be reunited with James Harden. The two were teammates in OKC in 2012, when the Thunder lost to the Miami Heat in the NBA Finals, and they're just the latest in a growing list of star duos to hook up this summer, following LeBron James and Anthony Davis with the Los Angeles Lakers, Kevin Durant and Kyrie Irving with the Brooklyn Nets, and Kawhi Leonard and Paul George with the LA Clippers. This summer's endless whirlwind of transactions has left even NBA players shaking their heads and predicting that the upcoming season could be the best ever.

Meanwhile, Houston Texans superstar defensive end J.J. Watt had a heartfelt parting message for Paul, thanking him for his impact on the Houston community at large.

Gonna miss you @CP3. Not many people know, but CP was literally the first celebrity to reach out and donate to the hurricane fundraiser. He had just recently been traded to Houston, called up and said he wanted to help. Very first one. Absolute legend.
