CHICAGO — Steven Adams is so big and has been in the Thunder organization so long, you forget he’s only 25. The first half against the Bulls on Friday, however, was a stark reminder of Adams’ experience. The two front court players assigned to stop him were 21 and 19, and Adams treated them as such, scoring 17 first-half points. Adams had all 10 of the Thunder’s points in the first four minutes, finishing through contact that went uncalled for much of a physical first half. Adams finished with 21 points and 10 rebounds, but made just 3-of-7 foul shots as the Thunder finished 16-of-24 from the line (66.7 percent), costly in a 114-112 loss. For all of Adams’ first-half success, he struggled finishing through contact in the second half, shooting just 2-of-6 from the field. Second unit struggles For all the Thunder’s poor shooting in the first half Friday, Dennis Schroder and Hamidou Diallo weren’t to blame. Schroder scored nine points in the second and finished with 19, finding holes in the Bulls defense on drives and rhythm on his jump shot. In his second game back from a left ankle sprain, Diallo looked much better, skying for an offensive rebound and a powerful dunk in the first half.
