Defense - Don't switch bigs on to Curry and Klay. It's just a bad move. It not only leaves the bigs open to the side-step three - like he did to Ibaka and Adams all series - but it also leaves the bigs on smalls downlow which not only is bad for our defense, but also is bad for rebounding.
Fight over the screens, and even step the big out a step or two if you need to on the pick and rolls, but recover to your man, and make that big handle the ball, or let Curry and Clay play circus performers all night.
Next, don't give them a lot of space to land. I'm not saying to put your foot under their landing spot. That is cheap and dirty and terrible. I'm saying they should be worried about it because of how close you are when they are landing. Turn your butt towards them so you don't have your toes out there for them to land on, but you should be right under them without foulling when Curry and Klay are shooting. All we need is for them to think about their landing for a milisecond, and they will miss the shot.
Finally, in the immortal words of Sasha Pavlovic, a great offense is sometimes your best defense. The Warriors live on transition threes to get them going on their streaks. Get high quality shots at the rim, crash the glass while maintaining some floor balance up top for transition defense, and make these guys play against your set defense.
Offense - Run Curry Run. I expect Curry will be defending JR. If that is the case, we need to run that man off of down screens until his legs fall off.
Bang Curry Bang. We have 3 or 4 bigs that will play serious minutes in this series. Each game, each of these players should set one wipe out screen and take the foul for wiping out curry. Just beat his little ass up physically all game, and don't let up for a second. Like Pat Riley said, keep fouling and they will eventually stop calling everything.
Switch Curry Switch. With Lebron as a capable pick or roll man, we should be aiming at Curry's man, and attempting to get Curry to switch onto Lebron, at which point you just head right at him, and when the defense collapses you can pass to our snipers. Not only is it good to go at him because he is a weak defender, but it will also gets into players heads when you are consistently targeting them on defense. When you are a shooter, having your mental game messed up is huge.
Long rebounds must lead to points - they are a jumpshooting team, which means they will have long rebounds. We have enough good rebounding down low that we should have someone sprinting down the court as soon as we have a rebound secured. Hopefullly, Curry is the only one back, and we can make him look Silly trying to guard Kyrie or Lebron in the open court. If not, we may be able to at least switch him onto someone because of the rushed transition Defense and problems manning up appropriately.
Lastly, GET PHYSICAL I know I've already said it about Curry, but this whole team is a bunch of preening posturing punks who are bullies until someone hits them in the mouth. If you can seriously rough them up (not to injure, just to make them feel you out there, and afterwards in the ice-bath) you will not only take their energy, but you will also get in their heads. DG will not be able to keep his cool and will absolutely be out of at least one game if we work this right, and if we can get them some negative momentum, I don't think they will be able to really recover. If the Thunder had any sense of killer instinct the Warriors would already be fishing.
Let's finish the job.
