Dude, that's exactly why he doesn't qualify.
Because, even despite that, he doesn't flame out early in the playoffs every year, tbh.
If the Mavs close it out, it will be Luka's 2nd WCF vs SGA's 0; and I don't know if you realize this because Luka has been tearing it up since he got to the league, but both are 6 seasons veterans. In fact, SGA is older than Luka. How can SGA be considered better, having accomplished way less and being eliminated by Luka?
Sorry to break it to you, bro, but you're kind of racist. At least colour biased, tbh.
