I wouldn't say it's an OKC thing as much as it is an SGA thing.
The T'wolves series last year was an insane joke. Just constantly pushing off as blatantly as possible, and not only doesn't get called for an obvious offensive foul, he gets rewarded with FT.
OKC is a good team, and they were the best team in the league last year, and probably are again. And SGA is a great player. I could even handle it if it was just a lame style of play and he flails and draws legit fouls. James Harden feeling a guy hand check him, so he quick goes up with a shot to draw a foul is bad to watch, but at least it's an actual defensive foul.
The level to which SGA initiates contact on offense in a very much illegal way and somehow ends up getting the defender a foul is really hard to watch.
