If you are questioning Oklahoma City Thunder star Russell Westbrook's ability to lead a team, well, join the club.

What has gone from just an informal discussion in fan circles has now turned into an open debate among NBA front offices, as many are legitimately wondering whether or not a club led by Westbrook can win a title following the Thunder's latest playoff flameout.

One veteran Western Conference executive thinks that Westbrook is an incredibly talented player, but he is not sure if he is true winner:

“He's a transcendent player, but I'm not convinced he's a transcendent winner,” said the executive, according to Howard Beck of Bleacher Report.

The Thunder were just bounced out of the first round for the third straight year, as Damian Lillard's 50-point performance capped by a buzzer-beating three-pointer sent the Portland Trail Blazers to a 118-115 victory over Oklahoma City on Tuesday night, resulting in a five-game series win for the Blazers.

While Lillard was brilliant, Westbrook labored.

Yes, the 30-year-old notched yet another triple-double in an ever-growing line of them, but he shot just 11-of-31 from the floor. During the series as a whole, Westbrook shot just 36 percent from the floor and 32.4 percent from long distance.

It marked the end of what was one of the least efficient seasons of Westbrook's career, as he made just 42.8 percent of his field-goal attempts, 29 percent of his triples and 65.6 percent of his free throws during the regular season.

Westbrook has made eight All-Star teams, but at some point, you have to wonder just how conducive his style of play is to winning.
