Building an NBA championship contender is a process, Sam Presti keeps saying. Not an event. A process. OK. I get it. I bought into the brainwashing long ago. But we interrupt this process to bring you an event. A watershed, momentous, historic event. Kevin Durant announced Wednesday he will sign a five-year contract extension that keeps him in Oklahoma City through spring 2016. Which could lead to another day that most definitely is an event: an NBA championship celebration in downtown OKC sometime in the next six years. Get that MAPS3 downtown park built quick, city fathers. We will need a place to gather if Durant and the guys win the NBA Finals some June soon. A title is not assured. There are no guarantees. The NBA is no soup kitchen, handing out a Larry O'Brien Trophy to any franchise willing to stand in line. The Thunder will stumble plenty in coming playoffs. Disappointment is the rule, not the exception, even for the most perennially competitive franchises. Go ask our friends in Salt Lake and Phoenix. But this much we know. Had Durant decided to bolt at his first opportunity, the NBA championship would have found its way to Mars before it hit OKC. Instead, Durant has pledged his future to the Good Ship Thunder, and it's not kooky to think Oklahoma City can have happy landing on a golden piece of hardware. Durant's declaration gives the Thunder instant stability. The future is set. The Thunder has secured its cornerstone. Which means the process can continue. The development of players (Durant included). The retention of players, which only gets easier when a player of Durant's caliber says he likes what's going on in Thunderland. The recruitment of players, at least in the future, when the Thunder might need to secure help to reach the summit but will do so with a plan, not with the clueless frenzy you see in the current marketplace. Don't forget. The Thunder arrived at this event through a process. A lot of little steps arrived to make Durant, one of the world's five best players, want to play long-term on the Oklahoma prairie. Cultivated relationships, from teammates to management to coaching (boy, that Scott Brooks-in-for-P.J. Carlesimo move looks better every day) to the fans. That's right, Boomtown. Pat yourself on the back. This week in Orlando, Durant reminisced about the Laker playoff series in April: "When I walked out on the court for Game 3 and seen that crowd, it was unbelievable. That's something I'm always going to remember.” The process also included the Thunder culture, which Presti has implemented, with players treated very well but the players responding by working hard and being solid citizens. Durant has been no small part of instilling that culture. "My teammates, I can't say enough about them,” Durant told our man Darnell Mayberry on Wednesday in Orlando. "I've seen a lot of different guys in the league and I've heard a lot of different stories in the league, but I've never heard a story like ours. How close we are and how young we are and how hard we play. "My teammates are a big factor in that. I'm just excited to be a part of this organization for a while.” And all that process led to this week, when the Thunder, a franchise without deep pockets and in a small market, made an $85 million investment in Oklahoma City's NBA adventure. And Durant signed on, he says, one minute after the offer was made. A significant commitment from team to player. A significant commitment from player to team. This was an event that is worthy of celebration, perhaps not with a parade but at least with a toast, because it shouts down the skeptics who said Oklahoma City couldn't keep a superstar like Durant. This event stamps the amazing Thunder success as sustainable. So raise a glass to Presti and chairman Clay Bennett, to the city and to the state, to the fans who spent big money and screamed big cheers, and mostly to the tall 21-year-old who, unlike the other superstars on the NBA stage, is low-key except when he's on the hardwood. Celebrate the signing of Kevin Durant. Then settle down. The process resumes.
