The Boston Celtics are building something promising. After ripping off the Brooklyn Nets in the heist of the century—the Pierce and Garnett trade—Boston added a bevy of young prospects in this year's draft. They'll join Isaiah Thomas, Jae Crowder, and company under the tutelage of Brad Stevens. For a minute, it looked like the Celtics might add a top-five player to the mix, too.

Crowder felt great after Boston’s free agency pitch meeting with Kevin Durant this summer, and some reports even stated the Celtics were the front-runner. Durant, of course, elected to sign with the Warriors, and Crowder is now salty.

He says the Celtics gave away their game plan for beating the Warriors, and Durant took it with him to Golden State.

“We … told him basically the scouting report of how we guarded Steph and Klay – our entire game plan, basically,” Crowder said, according to MassLive. “That's what made me mad. We (expletive) told him everything we do to beat these guys, and we beat them, and he went and joined them.”

Durant has heard the criticism from pretty much every angle, and he's seemed to tune it out well, but this feels more personal than most—aside from Russell Westbrook's beef, obviously.

"I felt like afterward, I was talking to Isaiah, like maybe after you sit back, you shouldn't have told him everything, but who the (expletive) thought he was going to Golden State, realistically?" said Crowder, who clearly overlooked the copious reports that Durant really liked Golden State. "It was like a slap in the face for us, basically."

Everyone wants a piece of the Warriors. We're gonna need the 2016-17 NBA schedule to drop ASAP.
