Could they? Probably
Would they? Toss up IMO
The tone of a healthy Cavs team wouldn't be the same as this one. With Kyrie and Love getting a lot of minutes the defense wouldn't be as tough nor would they be as gritty. GSW wouldn't be pressured as much as they are now so there offense would likely be better.
Nah, they'd have the option to go offense or defense, and the spacing for LeBron would improve dramatically, plus Kevin Love can score in the post against guys his own size like Barnes / Green.
Right now they can only go with a defensive lineup, with Love, Kyrie and Anderson healthy they'd be able to mix and match defensive/offensive lineups more, pull Kyrie and keep Love out there, pull Love and keep Kyrie. We saw what Kyrie is capable of against the Warriors too, the Cavs wouldn't fall apart like they do now when LeBron goes to the bench if they had Kyrie/Love.
They were just as good as the Warriors after the trade for Mozgov, slightly better in some respects too.
