On a career night, Russell Westbrook emptied his soul before the Chesapeake Energy Arena faithful. However, in an unforgettable encounter, his Oklahoma City Thunder fell 126-121 to a determined Portland Trail Blazers grouping.

Westbrook slashed, bounced, and sauntered his way to a career-best 58 points on 21-of-39 shooting. Unfortunately, his late attempt to tie the contest bounded off a remorseless back iron.

That costly miss would be all the separation a red-hot Blazers grouping would need to preserve victory.

In a make-or-miss league, Portland knocked down 55% of its shots while placing seven players in double-figure scoring. Reserve Allen Crabbe led Portland with 23.

Meanwhile, Damian Lillard (22) and CJ McCollum (21) checked in with 20+ point performances. A short Blazer bench combined for 49 points, and eight of the team’s eleven makes from deep.

For Oklahoma City, returning Victor Oladipo netted 16 points (4-5 3PM), and Enes Kanter added 11.

Following a season’s best 40-point opening-quarter burst, OKC’s offense cooled as its defense struggled to maneuver Portland into uncomfortable territory.

Consequently, the Blazers attacked a prone Oklahoma City rim at will while tallying 50 points in the paint. Having won three straight —and three of four this season vs. OKC— Terry Stotts’ crew (27-35) now sits 1.5 games behind eighth-seeded Denver for the West’s final playoff slot.

Meanwhile, Oklahoma City’s defense again floundered as Donovan’s bunch dropped a fourth-consecutive contest —each to below .500 iterations.

On a tough-luck night, OKC employed a full roster for the first time since Jan. 26. Unfortunately, this was not enough to rekindle Oklahoma City’s (35-29) winning spark.

THUNDER WOES

Defense: Once a hallmark of Coach Billy Donovan’s team, the Thunder has disappeared defensively in its four-game slide.

Once a hallmark of Coach Billy Donovan’s team, the Thunder has disappeared defensively in its four-game slide. Steven Adams: Adams (1-1 FGM, 2-of-5 FTM, 3 rebs) was caught in no-man’s-land several times on defense and left valuable points at the line in a closely-fought contest.

Thunder Bench: OKC’s reserves lost the battle to Portland’s bench in lopsided fashion. Not only did the Blazers subs outscore Oklahoma City’s 47-25, but the Thunder reserves committed ten turnovers and appeared generally out of sorts all night.

THUNDER PRO’S

Russell Westbrook: Short of making a couple of late three’s, there was nothing more Westbrook could have done to will the Thunder to victory on this night.

Unfortunately, vs. OKC, the Trail Blazers performed like the crew that gave Golden State fits in last spring’s playoffs.

With another loss to a team clinging to playoff life, questions now abound concerning the state of Oklahoma City Thunder basketball. While Russell Westbrook provided a memorable showing as OKC’s offense clicked, the defensive woes were undeniable.

Further, the Thunder has squandered precious opportunity to ascend the playoff ladder.

Now a daunting challenge looms for Thursday night as San Antonio enters Chesapeake Energy Arena.
