Repost of what I said before
The GS offense will EAT CLE defense alive. The addition of KD is the reason why.
H. Barnes, while good, is no KD. His shot didn't fall last year and the Cav's left him alone once he hit that 3p line. KD is going to have to be defended by either Lebron or KLove because of his size and speed. Frye and Thompson are too slow and Shumpert and Jefferson are too small. Let's just assume it's LBJ because it always has been.
That means Steph will have to be covered by Kyrie (yikes), JR (who is surprisingly decent this year at D), Shumpert (better on Klay IMO given size) or Thompson. We can cross Thompson off that list, he'll have to cover Dray or Javale, leaving Kyrie, JR and Shumpert. Shumpert won't start, so it'll be either Kyrie or JR covering Steph to start. My guess is JR as he is better than Kyrie at D. They'll also want to keep Kyrie fresh for offense and chasing Curry around the court is sure to tire him out.
That leaves Klay to be covered by Kyrie or Shumpert. Shumpert doesn't start (and likely won't) so it means Kyrie on Klay. Klay has the size advantage here so there will need to be assistance if Klay tries to post him up.
Then there is Draymond to still worry about. Assuming LBJ is on KD, that leaves Love or Thompson. This isn't a bad match-up, but Dray is much more physical than Klove and can stretch the floor as well. That means Klove can't come over to help protect Kyrie when Klay drives or posts up.
That leaves Thompson on Javale which won't really matter because Javale is a rim guy, not a mid-range shooter. But because he is a 7 foot rim guy, Thompson can't afford to leave him alone. He needs to body him up and not let him get easy buckets from oops.
With KD, Steph, Klay, and Dray on the floor, they can run the perimeter like the Celtics did and cause switches that will be optimal match ups for O and bad for CLE D. CLE can't sag off on GS on the 3pt line like they can with the Cs, they have to play up close. But Steph, Klay, KD, and Dray can all create their own shots. Only Al and sometimes AB can with the Cs when IT isn't playing.
This means the CLE D will have to be prepared for switches and communicate well. We've seen they can't do that, and frankly haven't all season. This isn't something they'll be able to switch on and off, it takes a full season to become good at.
My guess? You'll see a lot of pick and rolls, screens, etc. to create separation for shooters and we all know what GS can do when left open. CLE will have to counteract this by playing REALLY tight man to man, but that is really tiring for an entire game. It also leaves them susceptible to quick cuts to the basket because the CLE D will be watching the ball in case the defender gets beaten on the perimeter and the GS player drives to the basket as they slide over to help. It also leaves them open to perimeter shots as well.
All in all, it is a VERY unfavorable match up and we haven't even gotten to the bench.
Livingston will have to be covered by Shumpert. He is too long for Deron Williams and too fast for Jefferson.
Iggy will have to be covered by Jefferson, Shumpert is covering Livingston and Kyle Korver isn't athletic enough.
David West will command either Korver or Frye. I believe Korver is more likely as someone will have to cover Zaza.
As a result, Zaza will likely be covered by Frye given the size match up.
This is only 4 players, meaning there will likely be 1 of the starting 4 big names on the court as well. And the thing is, it can be any single one given the versatility of those players. Every single one can play at least 2 positions, in the case of KD and Dray, almost all 5.
I'm guessing a 5 game series. 4-1 GS. Cleveland wins 1 at home, GS wins the rest. (I'd change this to 4-0 now, given how dominant KD has been)
