Rockets strike 5-year deal to bring back Clint Capela — Sources from ESPN

The Houston Rockets have signed Clint Capela to a five-year, $90 million extension, sources told ESPN's Adrian Wojnarowski on Friday.

Capela was a restricted free agent. Had he instead signed a $4.3 million qualifying offer, he would have entered 2019 as an unrestricted free agent.

Now, all three will be back and likely together for some time; Paul agreed to a four-year, $160 million max deal to return earlier this month, and Harden inked a four-year, $228 million supermax extension last summer.

"Obviously we love the game of basketball, but to be able to provide for your family for generations, that's what we do it for," Harden told reporters in Las Vegas. "I've seen him work his butt off these last few years. He listens, learns, competes. I'm happy for him."

Capela's deal includes $1.5 million in likely-to-reach annual incentives and $500,000 in unlikely-to-reach incentives, league sources said.

The contract now pushes the Rockets' payroll to $136 million, the fourth highest in the league behind Oklahoma City, Golden State and Toronto. They now have a projected luxury tax bill of $21.4 million with 11 players on guaranteed contracts and two partial/non-guaranteed (Michael Carter-Williams and Zhou Qi).

Signing a player to the $1.5 million veteran's minimum would cost an additional $3.8 million toward the luxury tax. Houston still has $4.5 million remaining of the tax midlevel.

Capela finished second behind the Pacers' Victor Oladipo in voting for the NBA's Most Improved Player this past season. He was second in the league in blocks per game, eighth in rebounds per game and sixth in defensive win shares (4.1). His 42 double-doubles were eighth most in the league.
