The flaw here is that you're using stats to back up your argument but their stats are very similar (Hill last year to Lance this year).
You may think that I underrate Lance but I think many overrate him and think hes a superstar in the making. He's not going to be leading any team to an high winning level as the number one offensive option. Hes not a James Harden or anything close IMO.
As far as young 2guards, he's not better than Klay Thompson, Demar Derozean, and is prob about on par with Wes Matthews (not a knock on either guy, I like them both)
