Here are five things to watch in the Thunder's second preseason game Tuesday against Philadelphia (2 p.m. on NBA TV).
New developments: How will the Thunder continue to adjust to life without Russell Westbrook? In the exhibition opener, we saw a few new wrinkles, including an early halfcourt set that popped Serge Ibaka free for a 17-footer and a gorgeous sideline out of bounds play that left Kendrick Perkins wide open for a layup. The Thunder's early season success could be determined by how much the team is able to adjust and how quickly the Thunder will be able to adapt.
A strong start: In the opener, the starting five got off to a frustratingly slow start, staring at a 28-20 deficit to Turkish club Fenerbahce Ulker after the opening period. The Thunder appeared to lack rhythm and chemistry. It's an area the Thunder has got to figure out and quickly. The injury to Westbrook has left very little on the bench to bail out the starting five should the first unit have any slow starts.
Battle of the big men: Perkins dislocated his left ring finger in the opener, which forced him to leave the game just before halftime. His status is unclear for Tuesday. Rookie Steven Adams started the second half in place of Perkins and played relatively well. Hasheem Thabeet was the first true center off the bench, however, and Daniel Orton did not play. How will Thunder coach Scott Brooks manage the big man rotation this time?
Bench production: This will be something to watch for as long as Westbrook is sidelined. There is very little firepower in the second unit, and despite a strong effort against Fenerbahce, questions remain about how the Thunder will solve this mystery.
3-point shooting/defense: Game 1 wasn't pretty. The Thunder missed 12 of its 14 3-point attempts and yielded 10 on 28 attempts. It was hard to tell the source of the struggles. But if the Thunder's shooters can't step up, defenses will load up on Kevin Durant and dare OKC to fire away. And if the Thunder can't defend the 3-ball, there could be some nights where the offense won't be able to keep up without Westbrook.
