Guessing this is in Rivals, haven't seen it, but I'm presuming they're saying White is as good as Niang? Other than a few games here and there, I haven't seen much of White, but I presume this comes from Niang having a few off games and suddenly that's the player they think he is.
It's pretty much based on the fact that White's stats are better and he's on one rando NBA draft list. Not based on the fact that people watch basketball with their eyes open and can see the obvious.
