OAKLAND — The Cleveland Cavaliers arrived at The Finals as the most efficient offensive team in the playoffs by a wide margin, having scored more than 116 points per 100 possessions through the first three rounds. And they did it against three above-average defensive teams, including the team — Atlanta — that had the league’s best defense after Christmas.
In Game 1 on Thursday though, the Cavs were held under a point per possession for just the second time in the postseason. They shot 38 percent and had as many turnovers (17) as assists. And it was a good time to remember that the Golden State Warriors can be the best defensive team in the league when they’re locked in.
The key to the Warriors’ defensive success is their versatility, having multiple guys who can defend multiple guys. And on Thursday, the defending champs switched screens liberally in order to keep the Cavs in front of them.
That stifled Cleveland’s ball movement and had the Cavs trying to exploit one-on-one matchups. But the Warriors also double-teamed liberally and were quick to help whenever the Cavs got near the basket, where they shot just 17-for-35.
Those 35 attempts in the restricted area were a postseason high for the Cavs. And interestingly, one of the three times they topped that number in the regular season was their Christmas game at Golden State, when they shot 16-for-40 in the restricted area.
“I thought we did a good job of challenging a lot of shots,” Warriors coach Steve Kerr said Friday. “I thought they missed a couple that they would normally make, but all in all it was a good defensive effort.”
The Cavs can beat you both at the basket and from beyond the arc. In Game 1 of the conference finals, the Toronto Raptors focused on slowing down Cleveland’s 3-point shooting and gave up too many layups. On Thursday, the Warriors clearly made protecting the paint their No. 1 priority.
Here’s LeBron James backing down Stephen Curry after a switch, with both Festus Ezeli and Draymond Green (who’s leaving Kevin Love alone in the opposite corner) ready to help at the basket.
“When Steph switches on to him,” Kerr said, “he’s just got to do his best to stay in front, and we’ve got to help as much as we can, without giving up open threes. It’s much easier said than done, so we’re just doing our best.”
Three possessions later, James was backing down Klay Thompson after another switch, with Ezeli and Green again moving into position to help…
James has always been one of the league’s best finishers. But according to SportVU, his field goal percentage at the rim drops from 68 percent when there’s one defender there to 58 percent when there’s two or more. And his first instinct when he sees a second defender is to pass the ball.
“They’re switching 1 through 5,” Cavs coach Tyronn Lue said, “and when LeBron gets the ball in the post, they’re coming to double team. Also, when he gets the mismatch and he drives the basketball, they’re all collapsing. And we’ve got to make open 3s.”
But when the Warriors prioritize protecting the rim, it doesn’t mean that they’re willing to give up open 3s. All the attention that James was drawing after switches should have resulted in more open looks for his teammates, but the Warriors were on a string defensively and Green, in particular, did a great job of recovering out to his man after helping in the paint.

The Cavs, more often than not, were unable to take advantage. The Warriors rotations were generally great. But also, according to SportVU, 19 of Cleveland’s 21 3-point attempts were uncontested. The Cavs shot 37 percent (7-for-19) on those shots, down from a mark of 46 percent through the first three rounds.
Channing Frye was 24-for-40 (60 percent) on uncontested 3s before Thursday, but got just one look at one in Game 1. Cleveland didn’t use its floor-spacing lineups as much as it had in previous series. Thompson’s 31 minutes were the most he’s played since Game 1 of the conference semifinals and Frye’s seven minutes (including 2:24 of garbage time) were the fewest he’s played since that same game.
That was a clear sacrifice of offense for better defense. Thompson isn’t exactly Bill Russell out there, but Frye would have an even harder time keeping up with the Warriors’ ball and player movement. When Golden State used Green at the five against the Cavs’ second unit, Lue sat Frye down.
The question for Lue is whether Frye can make up for his defensive issues by making the Warriors pay for loading up on James. On Friday, Lue hinted that we will see more minutes for Frye in Game 2 on Sunday.
“We have to get more shooting out on the floor to try to keep those guys at home on the defensive end,” Lue said. “They do a good job of having a guy guard a ball and four guys are in the paint. So Channing will give us some spacing out on the floor. And just defensively, we’ve got to be able to make sure we have him on the right matchup.”
James believes the Cavs can’t waste time as their exploring those post-switch mismatches. Quicker decisions can produce more open shots.
“When you’re out there and they’re switching and you have a one-on-one matchup,” James said, “I think quick moves and not holding it as long is good. I think when you keep the ball on one side for too long and you’re pounding and pounding and pounding, then that can — too much of that won’t result in good basketball. It won’t result in good rhythm for everyone out on the floor.
“So there is a fine line. I’m okay with us having some isolation basketball if we’re going quick. But we’re holding the ball and we’re just staring down the defense and we’re staring down the ball, then it can become a problem for us.”
It wasn’t as big of a problem against their Eastern Conference opponents, who had to pick their poison, either dying by paint points or by 3s. The Warriors weren’t as highly ranked defensively as the Hawks were in the regular season, but they had the league’s No. 1 defense a year ago, they shut down the Cavs’ offense in last year’s Finals, and no team is more qualified to defend both the basket and the 3-point line.
“You have to be on a string,” Andre Iguodala said. “You have to know your rotations. You have to know where you want the ball to go, and you kind of influence the ball to go there. Meaning if you got a great shooter in the corner, you might want to influence the ball to go to the wing and, either we’re stunting or we’re X-ing out. It’s the shell defensive principles, but you got to have five guys on the same page. You got to be communicating in order for it to work.”
Most of Game 1 was a clinic in just that.
