The difference between playoff champs and chumps

Can a team's performance against better teams provide a way to predict playoff performance?

Robert Deutsch-USA TODAY

I was all set to go golfing last week when I went out to the garage and saw I had a flat tire. I changed it and took it in to get the tire patched, and as I waited, I read the October 13th edition of ESPN The Magazine and saw an article by Peter Keating (page 8) in which he made a case for playoff performance predicated on how well teams performed against the better teams during the regular season. I never would have read the article without having that flat tire -- the Lord does indeed work in mysterious ways.

I've written on this subject in the past, and it really holds true in football, so much so that Bleacher Report Afternoon Drive co-host Jason Goff (who hosts with Will Carroll) coined the term "bumslayer" to explain it. Jason was describing the 2012 Chicago Bears, a team that began the season 7-1 due to a relatively soft opening schedule, but faltered in the second half against better teams. They were bumslayers because they had no problem defeating the easy teams on their schedule but wilted against the better ones.

The central thesis of Keating's article was that teams that have success in the playoffs generally do well against the better teams during the regular season, and those who don't perform as well against better teams make early exits. He used this year's Angels as an example, citing that forty percent of their wins came against the worst teams in the AL (Red Sox, Astros, Twins and Rangers) but were only 9-11 against the other division leaders. We already know how that turned out. Logically, the argument makes perfect sense, since who are the opponents in the playoffs? Better teams.

I checked to see how well teams performed against teams who finished .500 or above going back to 1995 to see how far they advanced in the playoffs:

Series Rank
World Series 6.0
Lost World Series 5.6
NLCS 6.9
ALCS 6.3
NLDS 7.9
ALDS 5.9
Wild Card 15.3

In the 18 World Series played since 1995, the winners had on average the sixth-best record against good teams, the losers a smidge better, but overall the trend is clear -- teams with better records against good teams went deeper in the playoffs.

So what does this bode for this year? Here's how teams performed against teams with winning records:

Team G W L W% R RA pW%
Mariners 80 45 35 .563 292 260 .553
Orioles* 91 51 40 .560 380 351 .536
Tigers* 88 49 39 .557 399 361 .546
Cardinals* 72 39 33 .542 261 267 .490
Athletics* 84 44 40 .524 358 273 .622
Reds 90 45 45 .500 356 334 .529
Brewers 66 33 33 .500 259 302 .430
Nationals* 46 23 23 .500 169 190 .447
Royals* 89 44 45 .494 336 363 .465
Angels* 84 41 43 .488 341 329 .516
Yankees 86 41 45 .477 316 354 .448
Blue Jays 88 41 47 .466 361 366 .494
Giants* 58 27 31 .466 227 243 .469
Pirates* 72 33 39 .458 301 290 .517
Padres 77 35 42 .455 237 279 .426
Braves 62 28 34 .452 213 223 .479
Rays 106 47 59 .443 388 409 .476
Dodgers* 59 26 33 .441 225 226 .498

The Mariners were in the race right up to the final day of the season, and the Orioles and Cardinals are still playing. Part of the explanation is obvious -- teams can't win enough games to make the playoffs without beating good teams at some point. Conversely, the Angels, Pirates and Dodgers might have been bumslayers, teams who beat the teams they were supposed to beat but withered against stiffer competition. This could have been a factor in their early playoff exits this year. Then again, as of this writing the Orioles are down 2-0 and the Giants won the first game in their series. Trends don't always translate directly into actual results.

This table shows the rank for every World Series team going back to 1995:

Tm Year G W L W-L% RS RA pW% Rank
Braves 1995 59 36 23 .610 279 231 .586 1
Yankees 1996 75 40 35 .533 390 402 .486 5
Marlins 1997 74 40 34 .541 331 327 .506 4
Yankees 1998 64 38 26 .594 353 308 .562 2
Yankees 1999 65 39 26 .600 385 289 .628 2
Yankees 2000 85 42 43 .494 431 436 .495 10
Diamondbacks 2001 85 42 43 .494 395 367 .534 10
Angels 2002 71 32 39 .451 314 317 .496 10
Marlins 2003 101 53 48 .525 467 455 .512 6
Red Sox 2004 73 42 31 .575 433 366 .576 2
White Sox 2005 72 39 33 .542 270 289 .469 4
Cardinals 2006 47 21 26 .447 218 244 .449 14
Red Sox 2007 84 44 40 .524 428 381 .553 4
Phillies 2008 89 43 46 .483 430 385 .550 10
Yankees 2009 87 52 35 .598 484 411 .574 1
Giants 2010 68 30 38 .441 253 257 .493 15
Cardinals 2011 57 30 27 .526 251 251 .500 4
Giants 2012 62 31 31 .500 235 265 .445 8
Red Sox 2013 93 51 42 .548 448 375 .581 2

In many cases the World Series champions were the teams among the best against better competition. I highly recommend reading Keating's article, it's short and easy to understand, and as long as you have the magazine handy, flip to page 32 and read an alternate take on the World Series from Dan Szymborski. Either will do better than me -- I correctly picked the Giants to win their Wild Card game, and that's the extent of my correct postseasons picks. Three posts I wasted wrote describing postseason picks, and it's all up in flames. Maybe if I'd read Keating's article before I wrote them, I would have reached different conclusions.
