Golden State Warriors star Kevin Durant is obviously frustrated after they lost to the lowly Phoenix Suns on Sunday.

According to Sam Hustis of KNBR.com, Durant exploded and went off with a rant about the team's performance, especially after he went down due to ankle injury.

Heading to the locker room after the loss, KD was reportedly heard criticizing the team, emphasizing that they should be playing “championship level basketball” instead of the “stupid” way they displayed against Phoenix.

The Dubs bowed down to the Suns 115-111 after leading as much as 16 points in the game. In fact, in the first quarter, the Warriors were up 29-16.

However, Golden State collapsed in the second quarter, allowing Phoenix to score 40 points and cut the deficit to just one heading into halftime. It all went downward spiral for the team, especially after Durant got injured in the payoff period.

Kevin Durant has every reason to be frustrated though, as he was efficient for the Warriors throughout. Before leaving the game, the two-time Finals MVP tallied 25 points, two rebounds, three assists and two steals. He finished on 52.9 percent shooting as well.

His public rant won't help the Warriors at this point in time though, as it will do nothing but raise questions about his impending free agency.

If KD continues to show that he is unhappy with the team — despite all the success they had over the past couple of years — it will only affect their overall chemistry heading to the most important time of the year for them: the playoffs.
