UPDATE (Tuesday at 3:15pm) -- After speaking on stage at Tech Crunch in San Francisco, Kevin Durant opened up even more.
"To know that I affected Billy Donovan and the Thunder. Like, I love those people," Durant told Sam Amick of USA Today Sports. "That was just me being a total (expletive) idiot. I own up to it. I want to move on from it. It probably hit me probably harder than what everybody (thought). Everybody else was telling me to relax, to snap out of it, but I was really, really upset with myself more than anything.
"I haven't slept in two days, two nights. I haven't ate. It's crazy, because I feel so (expletive) pissed at myself and I'm mad that I brought someone into it...
"I was at home. I fell asleep watching football. I woke up, had charged my phone, and I just happened to look on Twitter. And I see, and I just don't remember it. I remember what I said and how I said it, but I just forget everything else. I forgot everything else. I was only focused on that convo, and that was unfortunate. I look like an idiot. My peers are going to look at me like an idiot. All the jokes – bring ‘em. I deserve it."
On Sunday night, Kevin Durant got himself into some trouble on Twitter.
A fan tweeted at him: "Man I respect the hell outta you but give me one legitimate reason for leaving okc other than getting a championship."
Durant's first tweet: "he didn't like the organization or playing for Billy Donovan. His roster wasn't that good, it was just him and russ."
Durant's second tweet: 'imagine taking russ off that team, see how bad they are. Kd can't win a championship with those cats."
Soon thereafter, Durant deleted the tweets.
On Tuesday morning, Durant was a guest at Tech Crunch in San Francisco and was asked about the incident.
"I do have another Instagram account, but that's just for my friends and family. I wouldn't say I was using that to clap back at anybody. But I use Twitter to engage with the fans. I think it's a great way to engage with basketball fans.
"But I happened to take it a little too far. And that's what happens sometimes when I get into these basketball debates ... I don't regret at clapping back at anybody or talking to my fans on Twitter. I do regret using my former coach's name and the former organization I played for.
"That was childish, that was idiotic; all those type of words. I regret doing that and I apologized to him for doing that. But I don't think I'll ever stop engaging with my fans. I think they really enjoy it and I think it's a good way to connect us all.
"I will scale back a little bit right now. Just focus on playing basketball. I want to move on from that. It was tough to deal with yesterday. I was really upset with myself."
