OKLAHOMA CITY (AP) — Thunder general manager Sam Presti took on a new look during the summer, just like the team he runs.The normally clean-shaven Presti returned from a summer trip with a neatly groomed beard."I went to Vermont and let it go for a little bit, and then when I got back, nobody seemed to have a problem with it," he said. "So I just kind of let it roll for a little while. I can't tell you this is something that's going to be around that much longer, but that is really the story behind it. So thanks, Vermont."If only the changes for the Thunder were as simple.Paul George's surprise trade request accelerated the end of an era. The Thunder sent George to the Los Angeles Clippers, then traded former MVP and scoring champion Russell Westbrook to Houston and rising star Jerami Grant to Denver. Now, for the first time, the Thunder enter a season with no players who were part of the team that debuted in Oklahoma City in 2008.The Thunder got a slew of draft picks in the deals and some players who can help immediately. Oklahoma City added veteran point guard Chris Paul from Houston in the Westbrook trade and Danilo Gallinari and Shai Gilgeous-Alexander from the Clippers.Paul, a nine-time All-Star, averaged 15.6 points and 8.2 assists for the Rockets last season. Gallinari, a forward, averaged a career-highs of 19.8 points and 6.1 rebounds per game last season and made 43.3 percent of his 3-pointers. Gilgeous-Alexander, a point guard, averaged 10.8 points and 3.3 assists as a rookie last season.There are some significant holdovers, too.Steven Adams has a chance to make a bigger name for himself. The 7-foot center averaged 13.9 points and 9.5 rebounds last season while shooting nearly 60% from the field."I'm really excited for him," Presti said. "I am really obviously a huge fan of his. I think that he still has growth left in his game. I think he has an opportunity to expand himself a little bit. He's the ultimate blocking, tackling player, but I also think that he's a talented player, and so he'll have an opportunity to do a little bit more."Guard Dennis Schroder is the top returning scorer after averaging 15.5 points per game last season.Forward Andre Roberson, one of the league's best perimeter defensive players, is back after missing the past 1 ½ seasons with a left knee injury. Presti said Thursday that Roberson will participate in training camp and is expected to play in the preseason."I'm excited, and I think everybody is excited, to watch and see how the team comes together through the year," Presti said. "I think this team has a significant amount of discovery within it in terms of just learning about the new players that we have and how they fit with the existing group."There is enough talent that Presti still sees the playoffs as a goal."What we want to do is be playing meaningful basketball at the end of the year," he said. "We want to try to do everything we can to put ourselves in position to optimize the group that we have, and there's just no shortcuts to that. It comes back to the commitment to the process that's in place and being willing to be patient with that as we go through, especially with this much change as we've experienced."___More AP NBA: https://apnews.com/tag/NBAbasketball and https://twitter.com/AP_Sports
