I agree with you, just talking tbh
Now is "not the time to a contender" with the Dubs as currently constructed. Now add the Rockets to the mix as they have the same championship window - as you have correctly alluded to.
As currently constructed, our most "seasoned" young gun is 23. We should sit back and develop these guys but we all know the Lakers won't do that. Short of poaching KD, there is nothing we can realistically do to get on their level short of raiding our young talent for a star or two. That doesn't work. Look at OKC. Top heavy and no bench. Anybody think they got a shot at the Finals? You gotta have depth or else you burn out your stars playing them too many minutes. This is what happened to Bin Harden last year.
