Nate Duncan argued the complete opposite in his over/under pod.
While they may be deeper than they were in the Durant era, I wouldn't consider them deep and they don't have the top-end talent those Warriors teams had with KD gone and Klay injured. How many established NBA players do they have? Curry, Dray, D-Lo, Looney, WCS, and maybe Burks?
The Warriors never had top-end talent as much as folks think they did; their 73-win squad was Steph, Draymond, and Klay, and then a bunch of role players, hell, most folks think Draymond was/is simply a role player too. I mean, let's face it, they didn't
win because they were more talented than every other team, they won because Steph is like having an extra player on offense, Draymond is like having an extra player on defense, and most importantly - their chemistry (which I'd argue is unparalleled in the history of the game).
I honestly believe that the loss of Iggy is going to affect them the most, after all, he was the presence that kept everyone and everything on an even keel on and off the floor. They're not going to be able to replace him no matter what they do, so if they don't meet the standard to which I think they should, it won't be because of a lack of talent, it'll be because they no longer have that type of veteran leadership.
I can't imagine their defense being any good and the lack of shooters puts the impetus on Curry to produce a season similar to his MVP years.
I definitely think there is cause for concern over their defense, but they got younger and more athletic in the offseason, and the nucleus of their defense (Draymond and coaching staff) is still there, which should aid them as they transition over to this new era, so to speak. And similar to what I said above, Steph and Klay have basically been the entire Warriors shooting depth (Draymond was their next best 3-pt shooter in 2016), and while Dlo certainly isn't on par with them, he's an adequate consolation prize, and they've got greater shooting talent, overall, than they've had in the past: Burks, McKinnie, Poole, Paschall, Evans etc.
