Durant, Curry and The Rest of the Warriors Something is Not Right, KD Will Never be a Champion

Yes, The Golden State Warriors is on the top of the standing and their newly acquired superstar is doing what he is supposed to be doing but some people still find something wrong to talk about. ESPN veteran sports analyst Stephen Smith has been critical against Kevin Durant and that he thinks KD will never be a champion.

00:36 - Durant gets questioned after he has a great game, but possibly choked at the end
03:00 - KD after the game, says he didn't fall on his own & postgame locker room
05:30 - Steph Curry Frustrated Postgame
06:45- Steve Kerr on KD's final seconds and what he means for the team

Golden State played well, The Cavaliers played well. It seemed like the Cavs just got unlucky in the first three quarters - Jefferson was 0/6, Shump 0/6. The ball simply wasn't falling. On the other hand the Dubs even with Curry staying cold - were doing very well.
Got their massive lead, fell asleep just as the ball started falling for the Cavaliers and blew it.

Immediately after Stephen A. Smith got on KD's ass, but actually bringing facts to bolster his argument. In his opinion Kevin Durant is not championship material right now, does he have a point?
KD himself humbled and frustrated after loss explains the last few seconds and what actually happened.
Stephen Curry was having a bad game to begin with and the fact that he got (illegaly) taken out in the last few seconds did not help at all.
