The Rotisserie system is not without its faults, which is why we feel impelled to tinker. But there is one thing that we rarely tinker with. The entire system for evaluating teams in a Rotisserie league has become nearly sacrosanct. The ranking of statistics, by category, and then the assigning of ranking points to determine the standings, is a fundamental component of the game's design. And probably the most deceptively inaccurate component of the game. This method of ranking teams -- or the ranking of anything -- distorts the truth. Tiny differences in the numbers can be magnified; huge variances can be minimized. Let's take a simple test league as an example, a 4-category, 8 team league: HOME RUNS RBIs Team No. Pts Team No. Pts ==== === === ==== === === ONE 200 8 THR 905 8 TWO 198 7 ONE 856 7 THR 196 6 FIV 840 6 FOU 187 5 FOU 831 5 FIV 152 4 TWO 821 4 SIX 151 3 SEV 807 3 SEV 150 2 EIG 806 2 EIG 149 1 SIX 766 1 STOLEN BASES BATTING AVERAGE TOTAL Team No. Pts Team BA Pts Team Pts ==== === === ==== === === ==== === TWO 179 8 ONE 287 8 ONE 27 SIX 170 7 THR 286 7 THR 26 FOU 165 6 SEV 282 6 TWO 22 THR 160 5 FOU 277 5 FOU 21 ONE 151 4 FIV 276 4 FIV 17 FIV 150 3 TWO 272 3 SEV 13 SEV 120 2 EIG 271 2 SIX 12 EIG 118 1 SIX 270 1 EIG 6 A nail-biter in this league, right? Sure was. Team ONE eked out the league title, backed by narrow victories in the HR category and finishing just ahead of Team FIV in stolen bases. Meanwhile, Team THR gave a valiant effort, falling just short in HRs and batting average while crushing the opposition in RBIs. And look at poor Team EIG, dead last and the furthest distance that any two teams are separated in the standings. But that's deceptive. With just three more HRs, two more RBIs and three SBs, EIG could have conceivably picked up six points on their own, while dropping the two teams ahead of them enough to sneak into sixth place. A net gain of about nine points -- a 33% swing in ranking points -- all for the want of one extra HR and one extra SB every two months. So this particular set of standings reflected an exciting race. Here's another set of standings... HOME RUNS RBIs Team No. Pts Team No. Pts ==== === === ==== === === ONE 232 8 THR 883 8 TWO 188 7 ONE 880 7 THR 186 6 FIV 828 6 FOU 182 5 FOU 822 5 FIV 160 4 TWO 820 4 SIX 159 3 SEV 817 3 SEV 156 2 EIG 792 2 EIG 144 1 SIX 790 1 STOLEN BASES BATTING AVERAGE TOTAL Team No. Pts Team BA Pts Team Pts ==== === === ==== === === ==== === TWO 179 8 ONE 290 8 ONE 27 SIX 175 7 THR 281 7 THR 26 FOU 164 6 SEV 280 6 TWO 22 THR 163 5 FOU 278 5 FOU 21 ONE 151 4 FIV 277 4 FIV 17 FIV 143 3 TWO 276 3 SEV 13 SEV 130 2 EIG 271 2 SIX 12 EIG 108 1 SIX 270 1 EIG 6 Um... same standings. Same number of total league HRs, RBIs and stolen bases. Anything but a close race. Team ONE crushed the opposition in HRs and BA, held large mid-standings leads in the other categories, and fell just short of first place in RBIs. Meanwhile, TWO's performance was a lot closer than the four points they fell short of second place would suggest. And Team EIG? Deservedly in last place. How can two sets of identical standings describe two completely different realities? Therein lies the problem with this type of evaluative system. The inherent deceptiveness when you use ranking points makes it more difficult to accurately evaluate teams, or anything that looks at multiple choices. What's worse, writers often use this type of system to support arguments in other analytical venues. You will see fantasy player draft lists constructed using ranking points. You will see companies publish comparative analyses of different services and use ranking points designed to support their promotional hype. Heck, the Elias Sports Bureau feeds Major League Baseball ranking points to determine whether players are Type A, B or C free agents. And all of them are feeding you garbage. They say that numbers can be manipulated to reflect the particular reality you want people to believe. Ranking systems like this are pure “razzle dazzle.” The most amazing part about all this is that the remedy to the problem is exceedingly simple. If we were to scale the ranking points based on each team's relative productivity in each category, we would create a far more accurate picture of how the standings shape up. For the league above, we'd give the first place team in each category 8 points, the last place team 1 point, and then scale all the other teams in between. This would be done by first calculating the spread between first and last place (say, 51 HRs). Then we'd take the distance each team is from first place, divide it by the total category spread, and multiply by 7 (the marginal difference between finishing in first versus last). The resulting value would be subtracted from 8 to determine the true ranking point value. Thusly... HOME RUNS Team No. Pts Calculation Pts ==== === === ================= === ONE 200 8 8.0 TWO 198 7 8 - (2 / 51) * 7 = 7.7 THR 196 6 8 - (4 / 51) * 7 = 7.5 FOU 187 5 8 - (13 / 51) * 7 = 6.2 FIV 152 4 8 - (48 / 51) * 7 = 1.4 SIX 151 3 8 - (49 / 51) * 7 = 1.3 SEV 150 2 8 - (50 / 51) * 7 = 1.1 EIG 149 1 1.0 This provides a much truer view of the spread in the standings. For the truly ambitious, you could even place a weight on the relative value of each category and in this way, make sure that stolen bases are not as important as home runs, for instance. Let's see how our tight race above would have shaken out had we scaled the standings points... HOME RUNS RBIs Team No. Pts Team No. Pts ==== === === ==== === === ONE 200 8.0 THR 905 8.0 TWO 198 7.7 ONE 856 5.5 THR 196 7.5 FIV 840 4.7 FOU 187 6.2 FOU 831 4.3 FIV 152 1.4 TWO 821 3.8 SIX 151 1.3 SEV 807 3.1 SEV 150 1.1 EIG 806 3.0 EIG 149 1.0 SIX 766 1.0 STOLEN BASES BATTING AVERAGE TOTAL Team No. Pts Team BA Pts Team Pts ==== === === ==== === === ==== ==== TWO 179 8.0 ONE 287 8.0 THR 28.9 SIX 170 7.0 THR 286 7.6 ONE 26.3 FOU 165 6.4 SEV 282 5.9 TWO 21.3 THR 160 5.8 FOU 277 3.9 FOU 20.8 ONE 151 4.8 FIV 276 3.5 FIV 14.3 FIV 150 4.7 TWO 272 1.8 SEV 11.3 SEV 120 1.2 EIG 271 1.4 SIX 10.3 EIG 118 1.0 SIX 270 1.0 EIG 6.4 Amazingly enough, Team ONE does not even finish in first place using this method. Their more distant finish in the two categories they did not win was enough to push them down the standings. But this is a more accurate view. It's bad enough that we've been married to such a system to determine our Rotisserie results. But you need to raise that red flag high when you see this method being used for more critical decision-support purposes. |
