New stats confirm you want to take shots at rim or from three

6 Comments

It’s a standard lament of old-school coaches and scouts — “the midrange game has died in basketball.”

Statistically, that’s a good thing.

It’s more complicated than that — there are good midrange and bad midrange shots, and those can change player-to-player — but by and large what you want your team to do is take shots right at the rim and from three point range, because that is where you shoot the highest percentage and where you get the most value for the shots.

Over at SBNation today the brilliant Tom Ziller put the results of a stat from a personal favorite site Hoopdata.com — expected effective field goal percentage — on a graph that roughly plots the quality of shots teams take. What the system likes is Denver’s style of play, followed by the Stan Van Gundy Magic — threes and shots at the rim. The graph does not corralate to good teams — the Heat, Lakers, Celtics Bulls and other teams took more mid-range shots than you might like but they have the players that can make them. It goes back to the comlications mentioned above, you’d like to reduce the number of midrange shots overall but if Kobe Bryant can get to the elbow area that’s a good shot he hits at a high percentage.

Oh, and the Bobcats take bad shots and miss them. Not sure we needed the graph for that.

You should read the entire thing, but Ziller sums up his findings this way:

If you look at the correlation between shot rate at each of Hoopdata’s specific ranges, we’ll see that the two efficient zones are not created equal. The percentage of a team’s field goals taken at the rim has a small positive (0.06) correlation with actual eFG. That’s essentially negligible. But the percentage of a team’s field goals taken from beyond the arc has a 0.48 correlation coefficient with eFG. Assuming a linear relationship, that indicates that about 23 percent of a team’s actual shooting percentage is explained solely by how frequently the team takes three-pointers.

Three-pointers rule the land. It’s also worth nothing the biggest problem with long-two pointers: that they are not three-pointers. The share of FGAs taken as long two-pointers has a -0.44 relationship with actual eFG. Shot shares at the two other inefficient ranges — short and mid — also have negative relationships with actual eFG, but with much, much smaller correlation coefficients. Why are long two-pointers such a problem? Check out the correlation between rate of long twos and rate of threes: -0.57. In other words, very few teams take lots of long twos and lots of three-pointers. So every long two is basically a three-pointer not taken. And three-pointers are important.

For those of you that don’t like math, let me sum up — threes and shots at the rim, that is the future. That is where teams have success, and threes matter a lot. Take a lot of long two pointers and your offense will struggle.

Cavaliers coach Tyronn Lue on Kyle Korver’s playing time: Brad Stevens ‘threw us for a loop’ by not playing Semi Ojeleye

LeBron James is obviously the Cavaliers’ best player. Cleveland’s second-best player? Usually Kevin Love, but Kyle Korver has made a case lately.

So, how did Korver play just 19 minutes, including none in the first quarter, in the Cavs’ Game 5 loss to the Celtics last night? That was his playoff low, besides Game 1 against the Pacers, when he was still recovering from injury.

Blame Boston coach Brad Stevens removing Semi Ojeleye from his rotation.

Cavaliers coach Tyronn Lue:

Well, initially, he’s been putting [Semi] Ojeleye in, so that’s been kind of Kyle’s matchup when he comes in the game. He didn’t play him tonight, so it kind of threw us for a loop.

This won’t slow the talk of Stevens being a genius. He neutralized one of Cleveland’s best players simply by not using a limited rookie.

Still, Lue’s strategy held some merit. Korver is a defensive liability, but Ojeleye’s offensive limitations make it hard to take advantage. Ojeleye’s biggest strength, his physical strength, is of limited utility in trying to stick tight to Korver on the perimeter.

In Games 1-4, Cavaliers with Korver on and…

Ojeleye on:

  • Offensive rating: 111.9
  • Defensive rating: 102.1
  • Net rating: +9.9

Ojeleye off:

  • Offensive rating: 97.0
  • Defensive rating: 109.5
  • Net rating: -12.5

That said, Korver is too good to plant on the bench. Other perimeter options – J.R. Smith, George Hill, Jordan Clarkson and Jeff Green (who actually played fine last night) – are just so unreliable. Lue shouldn’t just wait for the perfect matchup to use Korver.

But will Lue get it, anyway?

Stevens:

We believe in Semi and we think he’s a big, huge part of our team. It would not be a shock if he plays a ton for us in Game 6.

Lue better develop a plan for using Korver in Game 6 Friday, with contingencies based on Stevens using or not using Ojeleye. I wouldn’t trust Stevens’ declaration one bit, and Lue doesn’t want to get thrown for a loop again.

PBT Extra: Rockets showed defense, resilience, can Warriors show same in Game 5?

Leave a comment

Game 4 was an epic game, and the Houston Rockets proved they are a serious threat to knock the Warriors off the top of the mountain. They took Golden State’s big punch to start the game (a 12-0 run) and Stephen Curry haymaker in the third, cranked up their defense, got a great game from Chris Paul, and evened the series at 2-2.

Heading back to Houston, we can expect more of the same out of the Rockets Thursday night — they know a win in Game 5 puts them in a very dominant position in the series.

The question is, do the Warriors have another gear? That’s one of the topics I get into in this PBT Extra. For a few seasons now, the Warriors have been able to play lockdown defense and hit tough shots in the clutch, with Kevin Durant making them especially hard to stop, but in Game 4 when it got tight they looked tired and slow. Houston’s ball pressure threw Golden State off its game, and fatigue had set in for the Warriors. Can they not only go on big runs but slow down Chris Paul, James Harden and the Rockets’ attack?

Thursday night is going to be interesting.

LeBron James recalls six turnovers with striking precision (video)

LeBron James showed off his memory after the Cavaliers’ Game 1 loss to the Celtics, detailing every play of the beginning of the fourth quarter:

He was at it again after Cleveland’s Game 5 loss to the Celtics last night.

Asked about his six turnovers, LeBron perfectly described six turnovers:

The turnover LeBron very noticeably said went off Jeff Green‘s hands was actually assigned to Green. So, that meant LeBron omitted one of his own:

Still, this was incredibly impressive. It was also maybe a little passive-aggressive, the way LeBron notes the ball going off Green’s and J.R. Smith‘s hands.

So, it was quintessential LeBron.

Celtics top Cavaliers in Game 5, setting up Game 7 in Boston?

7 Comments

LeBron James and a couple Cavaliers teammates left the court well before the Celtics dribbled out their 96-83 Game 5 win Wednesday.

The Cavs are already moving on.

Game 6 will be Friday in Cleveland, and the Cavaliers – down 3-2 in the Eastern Conference finals – must win to avoid elimination. The way Boston has played on the road, it’s even easy to look ahead to Game 7, which is scheduled for Sunday in Boston.

Still, the Celtics bought themselves leeway with their decisive win in Boston tonight. They led by double digits the final 20 minutes, breaking the Cavs’ momentum after two straight wins in Cleveland.

“It’s tough going on the road, playing against somebody else in their house with their crowd,” said Jayson Tatum, who had 24 points, seven rebounds, four assists, four steals and two blocks tonight. “So, we were just comfortable. We came back home and defended home-court like we have all playoffs.”

Boston is now 10-0 at home this postseason – but just 1-6 away. Fueled in part by that historic split, no game in this series has been close. All five have been decided by at least nine points, and the average margin of victory – 18 – is in the 97th percentile for largest ever in a 3-2 best-of-seven series.

So, just as two big Celtics wins in Games 1 and 2 didn’t deter the Cavaliers, this one likely won’t, either. The Cavs should be heavily favorited in Game 6.

Beyond, if it gets that far? That’s a much bigger tossup.

Teams up 3-2 in a best-of-seven series have won 85% of the time. But Boston is missing a key reason it secured home-court advantage, including a chance to break the 2-2 at home rather than on the road – Kyrie Irving. And LeBron James is downright scary in a Game 7, even on the road.

The Celtics at least took care of business tonight, showing a far greater sense of urgency than Cleveland. Brad Stevens changed his starting lineup, inserting Aron Baynes for Marcus Morris, and tightened his rotation to just seven players until garbage time. Boston ran the floor much harder than the Cavs, decisively outrebounded them and beat them to loose balls. Even in altercations, the Celtics had a man advantage.

LeBron (26 points, 10 rebounds five assists and six turnovers) never made his presence felt in the way usually necessary for the Cavaliers to win. Cleveland’s four other starters combined to score just 24 points, two fewer than LeBron did himself.

After Boston seized control early, the Cavaliers made few adjustments in strategy or effort – as if they’re saving those for later.
