Jackson eviscerated the C’s defense with a career-best 27 points and handed the Celtics  (13-21) their fourth straight loss and seventh in eight games.
The NBA’s leading scorer, Kevin Durant , played more of a facilitating role for Oklahoma City (27-7), allowing the point guard his moment in the limelight. Durant still went for 21 points, eight assists, seven rebounds and three steals.
WHAT WENT WRONG
Jackson erupts: Prior to the game, much of the defensive consternation revolved around the matchup between Green and Durant. How Boston’s top defender, Avery Bradley , would defend Oklahoma City’s raw point guard was not a hot topic. However, Jackson, filling in for an injured Russell Westbrook , surprisingly torched the usually stingy Bradley for a career-high 27 points. The Boston College  product lit up Bradley in the first half. He scored 11 points in the first five minutes, and 19 over all in the half.
D on Durant: In one sense, the Celtics  defense deserves plaudits for not allowing Durant to break out for 46 points like he did in the Thunder’s previous win. But Durant’s 21 points (in just 27 minutes) against Boston did not properly reveal the impact he had on the game. He dished out eight assists, and when Oklahoma City was comfortably ahead, Durant went out of his way to pad his teammates’ point totals. Durant also pulled down seven rebounds.
Front-court production: While Crawford and Bradley kept Boston’s head above water, the Celtics ‘ starting big men did next to nothing to aid the guards offensively. Forwards Brandon Bass  and Jared Sullinger combined for 13 points compared to their combined season average of 25.5 points per game. Their sparse production was not a product of a dearth of opportunities; Sullinger finished 3-for-11 from the field and Bass 1-for-5. Sullinger fouled out in just 19 minutes.
WHAT WENT RIGHT
Bogans’ christening: It took close to the entire first half of season, but Keith Bogans finally found the score sheet. The veteran guard acquired by the Celtics  this offseason opened up the second quarter by burying a 3-pointer. Bogans last appeared in a game on Nov. 30 and had played in just 28 minutes over four games and attempted three shots. He saw playing time in lieu of backup shooting guard Courtney Lee , who was in the process of being traded Sunday.
Three-point barrage: A usually docile Celtics  3-point game erupted as Boston canned 11 3-pointers, the most since Dec. 10. The C’s defied a recent trend of poor 3-point shooting, particularly over the past three games. Boston shot a horrendous 14-61 (23 percent) in recent losses to the Hawks, Bulls and Pelicans. Crawford and Green authored the outburst with three 3-pointers apiece. Boston shot a nifty 8-13 from downtown in the first half to stay within 10 points.
Humphries: Kris Humphries again logged solid minutes off the bench, collecting 14 points along with three blocks and rebounds and two assists. In the last three weeks, Humphries has proved himself the most reliable Celtic off the bench. In his last 10 games, Humphries has averaged 9.8 points per game on 56 percent shooting, and 6.9 rebounds.
