Yea, the interesting thing is Curry is classified as a point guard but Harden always gets shooting guard comparisons (Kobe, Wade, Iverson), and similar has started with SGA; yet both have or will end up playing point guard for the vast majority of their careers. Luka is another one... he's a point guard but whoever they compare him to (it's a bit more ambiguous than the other two imo) it likely wouldn't be to other point guards.
If Magic, Oscar, and Curry get to be on the point guard list, then so should Shai, Harden, Luka. Might be a hesitancy to do so by pundits because it obviously/automatically would bump down a chunk of the Stockton, Nash, CP3, Kidd, Payton, Mark Price types... but those are the breaks.
And LeBron as well.
