Pho, I make no claims about whether the result last year would be different. This is another (and very complicated) conversation as it involves counterfactuals.
I take your point about D. But I still think you underestimate Kyrie and esp. Love. He gives you 16 pts per game on good FG% + 10 rbs; Moreover, (altho this claim is subjective) IMO his D improves in the playoffs.
Also, even if you think Kelly and KLove are average players, having depth has some value of its own. I mean, even if we were to agree that Kyrie and Delly had the same value, it is better to have two Dellys than one.
Anyway, I see your point is more about last year`s Finals than the players per se, and tbh I do not necessarily disagree. GSW was the better team anyway.
