nbawowy.com, we can look at a player’s efficiency and production when another player is either on or off the court. Here are the results for how some of the more well-known stretch fours affect the offense of their respective centers.
PPP=point per possession
PPS=point per shot
USG=percentage of team plays used by a player while on the floor
| Big Man Duo | PPP | PPS | FG% | USG |
|---|---|---|---|---|
| Al Jefferson without Josh McRoberts | 1.09 | 1.05 | 49.7% | 31.2% |
| Al Jefferson with Josh McRoberts | 1.13 | 1.07 | 51.4% | 28.2% |
| Nikola Pekovic without Kevin Love | 1.09 | 1.10 | 51.1% | 25.3% |
| Nikola Pekovic with Kevin Love | 1.19 | 1.18 | 54.7% | 23.5% |
| Anthony Davis without Ryan Anderson | 1.17 | 1.14 | 50.6% | 26.3% |
| Anthony Davis with Ryan Anderson | 1.24 | 1.28 | 61.7% | 23.7% |
| Samuel Dalembert without Dirk Nowitzki | 1.03 | 1.15 | 53.6% | 14.8% |
| Samuel Dalembert with Dirk Nowitzki | 1.10 | 1.20 | 56.9% | 15.6% |
| Brandan Wright without Dirk Nowitzki | 1.31 | 1.36 | 64.5% | 21.0% |
| Brandan Wright with Dirk Nowitzki | 1.42 | 1.43 | 71.2% | 16.5% |
The centers listed above were not terrible on their own, but the data shows that they become elite from an efficiency perspective when paired with a stretch four. Just look at Anthony Davis with Ryan Anderson, since I discussed it above. Davis is a great player regardless of his teammates, but when you put Anderson with him, he suddenly becomes one of the most dynamic offensive players in the league.
The term "stretch four" implies position, but as we move more and more to a position-less NBA, perhaps "stretch big" might be more appropriate. There aren't many players who we would deem a center that have the stretch capability, but the same offensive increase happens in the few cases. Take a look at how Tristan Thompson performed with and without Spencer Hawes, once Hawes was traded from Philadelphia to Cleveland last year.
| Big Man Duo | PPP | PPS | FG% | USG |
|---|---|---|---|---|
| Tristan Thompson without Spencer Hawes | 1.02 | 1.03 | 46.8% | 19.2% |
| Tristan Thompson with Spencer Hawes | 1.14 | 1.12 | 50.9% | 15.9% |
The effect is very real - big men are much more efficient when they are paired with a stretch big. And this is why every potential stretch big is being morphed into one. Kenneth Faried took 12 three-pointers total in his four years at Morehead State in college, but now is apparently on track to becoming a stretch four.
Rookie Julius Randle in Los Angeles was originally at the top of the draft boards coming out of college, mostly because of his ability to both play in the post and also step out and hit the three. When that didn't translate at Kentucky, he dropped to the seventh pick in the draft. If he had used that part of his game in college, he probably would've been in the top three.
The NBA is always trending. Advanced stats tell us that having two post players - unless they're elite and paired with elite guards (like Blake Griffin and Chris Paul) - isn't really the ideal way to build an efficient offense. We will continue to see big men learn to play like guards and guards play like big men.
That means players are becoming more identifiable by their skill set than their "position." And that's not a bad thing. When you know that Kevin Love is going to stretch a defense out to the perimeter with his shooting, that's a tangible offensive weapon you can build around. You can then fit all the pieces together. Find a guy who can run the pick and roll. Find a rim protector. Find another shooter.
Skill sets - not positions - are important. And if we're ranking the importance of skill sets, a long-range shooting big man is at the top of the list.
