Kevin Martin admitted to being nervous prior to tip-off Thursday night. The basketball didn't bother him. This, as he said, was a different type of nervous. It was his debut game as a member of the Oklahoma City Thunder, and the recently-acquired shooting guard just didn't want to mess anything up. "I've been the man the past eight years on my team," Martin said. "I'm coming into a system where I don't have to play that role anymore, which I'm very OK with. First and foremost, I just didn't want them thinking I was coming in here trying to be that guy. It's just about doing whatever I can do to win, and I think they respect that." While former Thunder sixth man James Harden is averaging a league-leading 41 points through two games, the veteran Oklahoma City acquired from Houston in exchanged for him just wants to fit in. Through two games, Martin has done just that. Martin has stepped in and immediately supplied similar instant offense off the bench as Harden did. Going into Sunday's game against Atlanta, Martin is third on the Thunder in scoring, averaging 17 points while ranking third in assists with 3.5 per game.
