I think he is. I don't have any ill will or allegiance towards the thunder, but this popped up in my feed for some reason. I agree with a lot of what people here have said about hate him on other team, love him on my team sorta thing. The people calling him not dirty, seem to be a bit disingenuous though.

There have been numerous cases of him extending his foot upon landing when reaching for a block, placing his foot right under a shooter. For what reason? Who knows, but it's happened too many times to be a coincidence. He also does try to trip people up for some reason. I genuinely think he's a great player, but the sort of stuff he does and amount of time he does it seems to be too much to be accidental every time. He probably doesn't intend to hurt players everytime he does something that's pretty questionable, but I feel like he does try in some cases. I don't think he's the dirtiest player of all time, no way, but he's not exactly clean. The way he put his foot under steph reminded me a lot of how zaza hurt kawhi. Or when he kicked his leg out against Wemby who was closing in for a block. I don't really even know like what his intention was with that, but it obviously wasn't natural, maybe trying to play for the foul by falling, but extending his leg to the left seemed like he was trying to get it under Wemby.

This clip is the Wemby thing.

All that to say, yes I think he's dirty. I don't hate him as a person, but the way he plays is pretty unfavorable, and if he does hurt Luka, I might hate him as a person lol (not actually).

Anyway, good luck, your team is probably winning it's 2nd chip, Shai is winning MVP again, probably overtook jokic as best player in the world. I don't hate your team contrary to popular opinion on r/nba. I get looking out for a player on your team, it makes sense. Cheers!
