Boo! Different Shirt!

A lot of factors can go into shaping a sports rivalry. There's shared history, geographical proximity, recent playoff match-ups, and so on. I suspect, though, that the biggest factor determining the strength of a rivalry is, quite simply, volume. Your biggest rivals will tend to be the teams you play most often.
It happens that some cities have "natural" rivalries with other cities, across all (or multiple) sports. Cleveland is not one of those. The Browns' biggest rivals, for example, are clearly Pittsburgh, Baltimore, and Cincinnati, in that order. But neither the Pirates, Orioles, or Reds registers as much of a blip on the Indians' radar, nor does any of those cities have an NBA team.
Meanwhile, an Indians fan might tell you that their closest rival is the Yankees, but would any Yankees fan say the same? I spoke to an anonymous source in the Yankees front office, who told me, "In... di-ans? Oh, right. The Indians are far, far down on [the Yankees'] list of rivals. Fuhgeddaboudit! I love New York!" The truth is, the Indians don't have any real classic rivalries, but if we could measure it objectively, their closest rivals would all be division foes. The Cavaliers, meanwhile, have had a recent mini-rivalry with the Celtics—something akin to the Browns' mini-rivalry with the Broncos in the 80s—but once again, their closest rivals come from within the division.
This got me to wondering—not because there is any inherent value or purpose in knowing, but just because I was curious—what is Cleveland's most "natural" rival, even in a watered-down field? More simply: what city do we face most often?
Of course, it wouldn't be fair to simply count up games played. For one thing, the Browns play the Bengals twice a year, whereas the Indians play the Reds six times a year. Surely, the Browns-Bengals match-ups should count for more than the Indians-Reds ones. For another thing, there are often imbalances in the schedule, so that in recent years, the Indians may have played more games against the Mariners (say) than the Rangers, but that does nothing to help us predict how often they'll meet in an upcoming, or given, year.
To illustrate how I'll calculate "match-up volume" (or "rivalry suitability," if you prefer), let's consider an example... say, Boston. Though the number of regular season Indians-Red Sox games will vary from year to year, the Indians average about 7.4 regular season match-ups with each AL East team, in a given season. That means that the Red Sox occupy about 4.57% of the Indians' 162-game schedule. Meanwhile, in a given NBA season, the Cavs will have 36 games to spread among the 10 non-division Eastern Conference teams—meaning they'll play the Celtics 3.6 times per year. Thus, the Celtics occupy 4.39% of the Cavaliers' regular season focus. Finally, in a given NFL season, the Browns will have 6 games to dole out to the 12 non-division AFC teams—meaning they'll face the Patriots 0.5 times per season. That means that the Patriots take up about 3.13% of the Browns' regular season schedule. To summarize:
Of course, the regular season is only part of the equation. We can also calculate the average number of playoff meetings between any two teams in a given year. Naturally, our methodology will consider all teams to be equally talented, so that the numbers will apply equally to the 2059 season (when—who knows—the Red Sox may suck) as to 2009.
This part of the calculation is considerably trickier, so I won't waste your time walking you through it. You'll have to trust me when I say that, in a given year, we can expect to see about 0.0391 playoff series between the Indians and Red Sox, 0.0667 playoff series between the Cavs and Celtics, and 0.0432 playoff games between the Browns and Patriots. We'll consider any playoff match-up, whether 7-game series or single game, to be equally monumental. Once again, in table form:
Okay, now we rank... but first, one caveat. I had to make some executive decisions about how to define cities. For example, I've got one city, "All NY/NJ Area," which includes the Yankees, Mets, Knicks, Nets, Jets, and Giants. That's a lot of teams, which means a lot of match-ups. Don't be surprised to find this Frankenstein monster of a city atop the rankings—and take it with a grain of salt. Meanwhile, I've got another city, "New York," which removes the Nets from that mix, and a third city, "New Jersey," which reinstates the Nets, but removes the Yankees, Mets, and Knicks. I have similar categories such as "San Francisco," "Oakland," and "All Bay Area," not to mention ones like "Milwaukee," "Green Bay," and "All Wisconsin." I just wanted to cover my bases. And I realize it's not perfect. What are ya gonna do?
First let's look at the top regular season ratings:
So how do we combine the regular season averages with the playoff totals, to get one super-ranking? No matter how we do it, it's going to be rather arbitrary and somewhat sloppy. For one thing, I have no idea whether regular season match-ups should be weighted as equally important, twice as important, half as important, etc., as playoff match-ups. So we may as well just weight them equally.
Using Boston as an example once more, here's how I'll combine the two numbers. Boston's regular season ranking (4.03%) ranks 11th, whereas its playoff total (0.1489) ranks 3rd. I'll average those two ranks (11 and 3) together, to get a "combined rating" of 7.0, which, as it happens, places Boston 4th on our quick 'n' dirty overall rankings. Observe:
Similarly, Chicago, Boston, and the Bay Area register high on our Cleveland list, but I'm not sure how high Cleveland would rank on their respective lists. Take Chicago, for example. As far as Cleveland is concerned, Chicago is equivalent to Detroit, but with an extra MLB team (the Cubs). And since the Cubs don't matter much to the Indians, Chicago ranks only slightly ahead of Detroit. But from Chicago's perspective, the Cubs matter just as much as the White Sox, which opens Chicago up to a whole slew of National League teams that will wash Cleveland down the list quite a ways.
What, then, do I take from our big list? Well, we might be justified in focusing the majority of our attention on New York, Chicago, and Boston, but our most "natural" rival, depressingly, is probably Detroit, followed by Baltimore. Also noteworthy is the fact that Cincinnati and Pittsburgh rank so poorly. The truth is that the Browns have a strong connection to the Steelers and Bengals in the regular season, but the geographical playing field is leveled once you get into the postseason. And despite what Bud Selig might tell you, those cities aren't especially important to the Indians, let alone the Cavs.
Okay, so there are no big surprises in these data. I was just curious, is all. In compiling these rankings, however, I did gain a new appreciation for some interesting quirks of the various leagues' scheduling and playoff formats, especially in Major League Baseball. For example, MLB is really giving the shaft to certain teams with its adherence to long-standing, but arbitrary, traditions. With fewer teams in the American League, a given AL team starts every season with a better shot of making the playoffs than a given NL team. And with fewer teams in the AL West than any other division, the A's, Angels, Mariners and Rangers get to start each season with even better postseason odds. Meanwhile, the poor NL Central teams are really at a disadvantage: each NL Central team has a 1/6 shot at winning its division, plus a 1/13 shot of winning the wild card in the event it doesn't win the division. That translates to annual playoff odds of about 23%. For contrast, the AL West teams start the year with 32% playoff odds. And in case you're curious, the AL Central and East teams have odds of about 27%; the NL East and West teams start at about 26%.
The real problem here is the weird insistence on having all interleague play take place at the same time. Baseball should model its regular season on the NBA's, with interleague series sprinkled throughout the season. If they did that, they could have 15 teams in each league, and 5 teams in each division, thus making everyone's playoff odds the same. I mean, does anyone find interleague play so exotic anymore that it must be treated like some kind of festival—a season within the season? I like the variety it brings to the schedule, but I can think of no conceivable reason why the Indians couldn't play their 2010 season opener in, say, Miami. (Besides, I'd like to see a game get snowed out there.)
Something else that I found curious, though not necessarily unfair, is the rule that prohibits division foes from meeting in the ALDS or NLDS. For one thing, this made my calculations of the Indians' average number of playoff match-ups with each American League team maddeningly complex. But more interestingly, the rule has the effect of making playoff series between division rivals surprisingly rare. For all of MLB's talk about cultivating rivalries (with the creation of the unbalanced schedule and the "rigged" assignment of interleague match-ups), it's worth noting that the Indians are almost five times more likely to have a playoff series against a Boston or a Seattle than against a Minnesota or a Detroit. In fact, the odds of an Indians-Twins ALCS are almost as low as the odds of an Indians-Rockies World Series.
I could go on further about the quirks of, say, the NBA and NFL seasons, but I've already strayed too far off my original topic. Point is, Detroit sucks. I think we can all agree on that. Stay Cleveland-y, Cleveland.
It happens that some cities have "natural" rivalries with other cities, across all (or multiple) sports. Cleveland is not one of those. The Browns' biggest rivals, for example, are clearly Pittsburgh, Baltimore, and Cincinnati, in that order.

Indians Cavs Browns sumAs expected, New York dominates both lists. But beyond that, I was a little surprised at how different the two lists are. I initially expected to find that regular season meetings correlate reasonably well to playoff meetings, but such is not the case (we'll return to this topic shortly). So while the expected geographic rivals (Chicago, Detroit, Cincinnati) dominate the regular season rankings, the second list contains some genuine surprises, such as Miami, Indianapolis, Toronto, and Oakland.

Sure, our teams face New York teams more than any other, but a rivalry should be reciprocal; that is, important to both sides. If I'd written a similar post about Philadelphia's natural rivals, or Atlanta's, or Washington's, or Detroit's, we'd likely get the same result: New York at the top. If Cleveland appeared anywhere near the top of New York's list, that would be a different story. But my guess is, that's not the case.
