Ok.
Its a bad team without him to be sure, but Dipo/Adams/Kanter with several defensive players isn't horrifying. And they are going to end up pretty close to the 45 win O/U that Vegas had before the season started. And a 6/7 seed (I'd bet 7th) isn't going to get it done.
OKC ranks #6 in the NBA in defense and #18 in offense. They win because of their defense. Period. He doesn't contribute in a meaningful way to that. They WOULD be a lesser offensive team, and substantially so without him. But propping a team up to the #18 offense isn't MVP caliber stuff IMO.
And all the stats you are quoting me are box score influenced stats. I have been attempting to showing how his stats have been pretty brazenly inflated and you are saying yeah, but this stat that uses all those inflated stats is high! Sure they are. No one is arguing the accumulations aren't impressive. Just that when you peek behind the curtain, they aren't as majestic as they would seem. He has carried his team to the #18 offense in the league with SIGNIFICANTLY BELOW AVERAGE efficiency, his defensive rebounds are inflated by 50%, and his team would be the lowest seed to earn an MVP since... Ever.
It doesn't diminish an impressive season and he absolutely should be starting the ASG. I just don't think he has a claim to be MVP.
