How can't you take them seriously? They won 44 games last year.They added Warren and O'Neale as well. Plus, Sharpe and Thomas should be a lot better. They have so many question marks it is hard to trust them, but if they actually put it together, I think they could legitimately contend. I don't think they will put it all together though and will probably be in the play-in again and make for a tough out for one of the top seeds, just like this year (except they will be better by the shear fact you'd expect Simmons and Harris to play).
Conservative games estimate
Irving 29 > 55
Durant 55 > 55
Simmons 0 > 55
Harden 44 > 0
Harris 14 > 55
Curry 14 > 55
Mills 81 > 55
Brown 72 > 0 ---- This is the biggest one
Thomas 66 > 55
Claxton 47 > 55
I'm sure Aldridge and Drummond can be replaced.
Looks like about 47-48 wins to me.
Warren should have a good bounce back season. My concerns for them is the fit of their additions. Warren is another high volume shooter who doesn't create for others and he will be looking to pad his stats for his next contract. Simmons, we know his issues, how can a guy who needs to dominate the ball and can't shoot fit with KD and Kyrie? At least Simmons should help them defensively, but they need to focus more on roster fit , add complementary players who fill in their weaknesses. Rumors are that they may add Melo too, which also doesn't solve anything for them.
I'm not rooting for them, but...
Harden is the major thing out, Kyrie and Simmons should cover that.
Harris healthy and Curry for a full season should cover Brown.
I hope they load manage all year and end up in the play-in, but I suspect they end up in the middle of the pack. Not true contenders but dangerous.
