U can't go wrong with either one, however; it's Curry for me by a solid margin.
I probably don't post enough to get POTY, but if u nikkas know my history, yall know I break the game down and U don't hate on nobody. So real talk, Steph gets the edge because as of right now, he has more of an effect in games than anyone in a long time. He is in the running to be called/labeled the most dangerous offensive player since 06 Kobe. Kobe's biggest advantage was his skill level. Kibe was a hell of an athlete, but his skills > his athleticism. Steph Curry is the most skilled player in the NBA, and that's by a LARGE margin. Right now, NOBODY comes close. Russell eats a lot off his athleticism, he may be the least skilled out of the top 10 players in the league (a list that's hard as fukk to make right now cause there is so much different types of talent).
Me personally, I will take skills over athleticism any day of the week. It's what made MJ the undisputed GOAT, and what keeps Lebron miles behind MJ and Bird still considered on an even level. Bron's lack of skill with ball handling, post game, and getting off clean jump shots will forever keep him behind MJ, and always keep Magic and Bird in the conversation with him. In contrast to that, Durant skill level could possibly put him ahead of Lebron if he ever gets a great team around him and wins 3 or more rings (needs to happen soon, will not happen next to Westbrook).
Back to the point. Steph is not an athletic monster like most of his peers, yet, he can do everything they can do because of said skill. Off rip, I I have heard any of you nikkas say that Steph only shoots jumpers, I can't take you fukk nikkas serious. Steph gets to the basket just as much as any of his peers and finishes at a % just as good as them also. Insted of using athleticism to finish over nikkas, his floater and flick layups are the best in the game. EVERYTIME Steph has been pressured this season, he beat his man off the dribble with ease and either pulled up from midrange (I don't think the nikka has missed a midrange jumper at all this season) or got all the way to the basket for a floater or a straight layup off the glass. nikka has numerous finishing moves at the basket on top of how he handles the ball away from the basket to get there.
Matter of fact, I'm blowed as fukk right now and I been sober for weeks. fukk yall nikkas, a wise man told me don't argue with fools

. Ole box score watching ass nikkas

, some of you nikkas are embarrassing
