Luka averages 28.7 pts 9.3 reb 8.7 assists. In his second year of his career
Harden avarages 34.4 pts 6.4 reb 7.4 assists.
Defensive numbers where pretty much the same. It is close Luka will end up having the better career in my opinion and I actually like Harden. But they are pretty close to each other talent wise.
