Wouldn't have been the difference between winning and losing but Joe Harris was a legit loss as well. He was miserable last year vs Milwaukee on offense, he makes some shots and they don't lose game 3 or game 7. But he has some actual size and wouldn't be as much of a defensive liability as Curry/Mills/Dragic are.
An Irving team is gonna need him to be the worst defender on the floor usually, if you got 1-2 guys worse than him against the top NBA teams, look out.
It'll be interesting to see how they use Simmons next year, people talk "Draymond role" but kinda leave out only 1 guy can actually do all that.
I wouldn't say they're done yet though....The Warriors had a fork in them and now they're back as a contender, LeBron looked like the sun was beginning to set then he won a title, stuff changes fast if things break right. East is pretty loaded now though.
