Kevin Durant was watching, and he liked what he saw.

According to Nets GM Sean Marks, the marquee free agent is a fan of how his new team plays. Marks shared on WFAN on Tuesday that Durant told him, shortly after he announced he was coming to Brooklyn, “I love the system. I love how you guys play. I see how hard you guys play … you were never out of games. We [the Warriors] could never take you guys lightly.”

Coach Kenny Atkinson’s relentless style of play was attractive to Durant, who signed a four-year, $164 contract with the Nets, as well as Kyrie Irving, who landed in Brooklyn on a four-year, $136 million deal.

“I’m not going to lie, there’s been a couple of times I’m definitely excited about — Kevin for sure, the whole group and really the challenge of getting all these guys together on the same page and watching how it unfolds,” Marks said. “I think that’s the magic and that’s the real special piece where you see elite talent … want to play together and see who’s going to sacrifice what and who’s going to bring what to the table and just see how they all mesh.”

While Marks found out about Durant’s decision on Instagram — “What we knew was we were either getting a teleconference call with Kevin that night or we were going to potentially get a meeting,” he said — there won’t be many more surprises with the 10-time All-Star.

“I think we all know what we are getting with Kevin,” Marks added “The talent is undeniable.”

It will most likely be another season before the Nets gets to see that talent back on the court, as Durant heals from a torn Achilles tendon that came about during the NBA Finals, though Marks isn’t putting a timetable on things. More importantly, he isn’t planning to rush the former MVP’s return, either.

“We’re certainly not going to rush him back,’ he said. “There’s going to be absolutely none of that. We have far too much invested in him, and we owe it to Kevin to get him back to 100%.

“This is entirely going to be a Kevin Durant decision.”
