I'll start by outright stating that I don't believe Kevin is trying to diss Kawhi, albeit the timing of the Tweet was unfortunate. I'm going to muse over the rhetoric, without necessarily trying to determine a conclusive argument:
I reflected on a recent female colleague's employer, where a male coworker that serves in the same position as her was promoted first, despite having been with the company a shorter time. I've met this coworker and he's not the sharpest tool in the box, but for whatever reason he was the better fit at the time. This event has left her bitter regarding her employment and open to listening to offers from competitors...
I bring up my friend's experience because her argument's mirrored Kevin's during the short exchange. Her individual accomplishments, vs. the predominately (entirely) male dominated management team that she works with. Her team isn't concerned with promoting her above their own level.
Kevin's emotional defense of Paul George reads like a subtext regarding his own discontent with systems that don't work to empower and boost their 'stars'.
I feel this Tweet expresses his own discontent with the system he plays in, but perhaps he lacks the personal vocation to express it outright.
I sometimes hear K.D.'s interviews, (such as the famous "servant") and I reflect upon our shared religious upbringings. It is possible that Kevin believes that through patience, deliverance shall be placed in front of him to take, but that's simply not possible with his current reality.
He has been the best player in the league this season and his individual accomplishments are not enough.
Another season has ended without success and while the rest of the league mulls over which superstar they'll add to their unit, we're still discussing which prospect we'd like to develop through the draft (as J.A. would famously say 'Thunder University').
The media loves to place a lot of pressure on Lebron, Phil, the Knicks, the Lakers etc. but perhaps it is time the pressure be placed on our management, instead of simply Kevin, Russell, Scott and Kendrick.
There are multiple teams willing to part with valuable talent, in order to sign a big agent, I would like to see the Thunder, if only for once discuss the offseason in a more competitive light.
