Over on The Twitter this morning, I took issue with some of the rationalizations people offer for their dislike of Duke's basketball team. To be clear, though I am a longtime fan of the team, I don't really care whether people like Duke -- I (quite obviously) don't play for the team, didn't go to the school, and have spent about 27 hours of my life in North Carolina. I do, however, take issue with obviously bogus rationalizations for that dislike, mostly because I am not a fan of obviously bogus rationalizations in general.
For example, I've seen people say they don't like Duke's basketball team because Duke is an elite, extremely expensive school. I'm not really sure what that has to do with basketball, but in any case: I never hear that complaint about Georgetown or Stanford or Villanova or Wake Forest, none of which are exactly easy to get into, and all of which are extremely expensive. And certainly not about an Ivy League upstart that threatens to win a few games. So I tend to doubt that's the real reason people dislike Duke. It's OK to dislike Duke just for the sake of disliking them. Really, it is. You don't need to make up a cover story.
Anyway, in response to my Tweet, a couple of people told me Duke is hated because they benefit from favorable officiating. Well, It just so happens that I've long considered the "Duke gets all the calls" meme a classic case of observer bias and of the distorting effects of conventional wisdom, so I figured I'd finally spend a few minutes spelling some of that out.
A couple of disclaimers up front: First, I'm not saying Duke doesn't benefit from favorable officiating -- I'm saying none of us really knows whether they do. Second: I'm not trying to convince you to like Duke. I don't care whether you do. I don't really get why people enjoy hating sports teams (unless they're coached by John Calipari) but I recognize that many people do -- so have at it!
OK. Here goes:
1. College basketball officiating isn't particularly consistent. Referees often seem to call interior play more tightly than perimeter play, or vice-versa. Different officials call games differently -- and even individual officials will show variance in foul-calling from game to game, and even within games. Finally, most basketball viewers aren't particularly good at correctly assessing what is and is not a foul -- they aren't experts, they don't always have good angles, etc. I can't prove any of that, but I don't expect anyone, save perhaps an NCAA referee, would seriously contest it.
2. Given all of that, if you're watching a college basketball game in which you have a rooting interest, it is incredibly easy to find yourself thinking "your" team is getting hosed by the zebras. Most people are more likely to notice questionable calls that go against their team than those that benefit their team -- and to react more strongly to them. This skews their assessment of the officiating.
3. I believe, as many people do, that referees tend to slightly favor players who have an established level of success. Michael Jordan got a ton of favorable calls; one of the iconic moments of his career -- his game-winning shot against Utah in the Finals -- probably should have been an offensive foul. Dwyane Wade, Larry Bird and countless other players have likely gotten a bit more leeway and "protection" from referees due to their established abilities.
Those first three points are, I would imagine, pretty uncontroversial. Moving on:
4. A lot of people don't like Duke. So a lot of people watching Duke games perceive them to benefit from favorable officiating even when it is not happening (per 1 & 2 above.) And Duke just might get more questionable calls that go their way than, say, Arkansas Pine-Bluff (per 3 above.)
5. That leads to a lot of people saying "Duke gets all the calls" -- which leads to a lot of people hearing "Duke gets all the calls."
6. Constantly hearing "Duke gets all the calls" leads people to expect Duke to get all the calls -- so, when they're watching a Duke game, they're more likely to notice a close call that goes Duke's way. People see what they expect to see. They then start saying "Duke gets all the calls," and the whole thing snowballs.
7. Finally, even if a viewer correctly and impartially assesses every call and non-call in every Duke game for several years -- enough to build up a significant sample size -- s/he is unlikely to have an accurate mental picture of the pattern that emerges. Think of it this way: When a player shoots a jump-shot, there's no subjectivity involved in determining whether it goes through the basket. Now, say you watched Hollis Thompson shoot 500 jumpers in games over the course of 4 years, but didn't keep written record of how many he attempted or made. Now: If you had to guess what Thompson's shooting percentage was, based solely on your observations of him over the years, how close do you think you'd come? I think you'd be lucky to come within ten percent of his actual shooting percentage. And that's a much, much easier task than keeping reliable-but-informal tally of highly subjective things like incorrect foul calls for and against a given team.
Now, none of that should really be controversial, either. Argue with it if you like, but you'll be arguing with human nature more than with me. It is important to note, however, that nothing above "proves" that Duke does not benefit from a disproportionate share of questionable calls. It is simply a reminder that the notion that Duke gets favorable treatment is nothing more than an impression created by unreliable observations -- much like the near-universal (but no longer operative) image of Tiger Woods a clean-cut good guy.
So what do I think? I think that nobody really has a clue whether any team gets a disproportionate number of bad calls over a statistically-significant sample, and that anybody who expresses much certainty on that front should examine the reliability of their conclusions, in part by considering the factors presented above. I don't find it hard be believe that elite programs get a few more calls than middling programs (see 3 above) though I doubt the disparity is particularly large, and even within programs, there is a disparity among players.
Duke is on television roughly 30 times a year in the District of Columbia, where I live. I've been a fan of Duke basketball since the late '80s (though, for reasons not relevant here, I am not particularly fond of Duke's coach) so I probably watch 20-25 of those games. I am obviously not an impartial observer of those games -- though I think my mild obsession with observer bias makes me less to jump to conclusions than many if not most basketball-watchers. I should also note that my biases extend well beyond being a Duke fan. I -- like most observers -- have biases about the style of play that I prefer and other factors, all of which go into my reactions to foul calls and non-calls. I like to see a relatively open style of play, without a lot of pushing and grabbing on the perimeter, for example -- and that, no doubt, affects my assessment of officiating. You really can't overstate the biases most of us bring to our assessments of how a game is officiated.
Speaking of pushing and grabbing on the perimeter: The one consistent pattern I have perceived in college basketball officiating over the years was a small one: I believe that in J.J. Redick's senior year at Duke, he was routinely fouled while working off the ball on offense, without a foul being called. He was constantly pushed and grabbed on the perimeter as he was trying to get open, well above and beyond what is typically allowed.* Of course, all of the caveats about observer bias I have spelled out apply here, perhaps most significantly including my distaste for that style of play -- and even if I'm right, the referees' approach to one player over the course of a couple dozen games says very little about their approach to an entire team over the course of many years.
I can't remember a college player who was more consistently said to benefit from favorable calls than North Carolina's Tyler Hansbrough. His offensive game often seemed to consist of slamming himself into a defender, either knocking him over and scoring, or drawing a foul, which led to him making approximately 19 trillion free throws. During his four years at UNC, I certainly indulged in my share of complaints about referees sending him to the line after he initiated contact and his defender did little more than fall over after being clobbered. But did he, over the course of the ten thousand or so possessions he was involved in, benefit from a disproportionate number of bad calls? I can't say with any confidence that he did. How could I? In fact, I kind of doubt he did in any significant way.
Finally, Len Elmore probably broadcasts a quarter to a third of the Duke games I see each year -- and in doing so provides the one of the best illustrations of the concept of "observer bias" I've ever seen. When a close or questionable call goes Duke's way, Elmore can be counted on to say something like "That kind of thing is why people think Duke gets all the calls." He'll sometimes say that even when he says he thinks it was the right call. But when a close/questionable call goes against Duke, Elmore either ignores it or simply says it was a close/questionable/wrong call. He does not -- not once, in all the games I've seen -- say anything like "That undermines the theory that Duke gets all the calls." The effect this has on viewers and on perceptions about Duke getting favorable calls should be obvious. (Anyone looking for an example of Elmore's conduct in this regard should
seek out a copy of the Duke-Temple game from Redick's senior year.)
* Two notes on this: First, note the specificity of my wording. It's possible Redick benefited from favorable calls once he had the ball, or on defense. I never noticed much of a pattern either way on that front; I'm speaking solely of his off-ball movement on offense. Second, I thought at the time that Coach K should compile a video showing the most egregious non-calls to combat the perception that Duke gets all the calls. Referees are, no doubt, aware of that perception, and if I were Duke's coach, I would be worry that they bend over backwards to avoid such perceptions.
UPDATE: One final thing, going back to the idea that people hate Duke because they get all the calls. Even aside from the question of whether that's an accurate perception of officiating, I think it's a bogus explanation. I remember widespread belief that Michael Jordan benefited from favorable calls. But I don't remember him being reviled for it. One more time: Go ahead and hate Duke if it makes you happy. But don't bother with the flawed rationalizations.
