I agree with both of you, though it should be noted that LeBron took way more grief in his final couple Cleveland seasons than Durant is taking right now. Do you remember how absurd the talking heads were during some of those Orlando/Boston series'? LeBron put up something absolutely absurd like 40-9-9 during that Orlando series, and all anybody could talk about afterwards was, "Why didn't he shake hands?". And I don't even want to regurgitate the details of the "LeQuit" narrative following the Boston series. He didn't play well, but the flack he took was still waaay overboard for losing to a Boston team that was far superior at three of the five positions.
And yeah, Westbrook is just infuriating, even if it's true that the shortcomings of Brooks has a lot to do with that. When you watch the composure that guys like Conley and Lillard play with, and then you watch Westbrook barrel into traffic and hoist reckless shots, his deficiencies become even more glaring. He's a very, very gifted player that just doesn't have the feel for the game - and probably never will - that Paul, Magic, Nash, Stockton, and all the other greats had.
That being said, yeah, Russ is constantly left out to dry late in the shot clock, and that definitely contributes to his poor shooting percentages. For as out-of-control as Westbrook looked last night, Durant has played that way the entire series, jacking long three's early in the shot clock, trying to barrel through traffic hoping for a bail-out foul call, missing shots he normally hits, etc. Tony Allen is a great, great defender, but Durant just looks completely shook whenever he's in the game. At this stage in his career, he can't be allowing somebody six inches shorter than him to be locking him up like this. He's going to have to go back to the drawing board this offseason and add to his game (particularly in the post).
