BASEBALL: 2010 EWSL Wrapup By Team
My annual division roundups, using Established Win Shares Levels (explained at the beginning and end of this post), are disastrously overdue, part of the general fallout of difficult personal times - between wrapping up my brother's estate following his sudden death in November and my dad's severe (and not unrelated) decline in health since the end of 2010, I've been up to my eyeballs in everything but time to spend on my job, family and blogging. Naturally, my baseball blog posts take the brunt of that - it's one thing to write about politics or music, since most of the time that takes is the writing time, but most of my baseball stuff requires a lot more investment of time crunching numbers.
That said, in the next few weeks I intend to get the EWSL "previews" done, maybe more of them than usual after Opening Day, if for no other reason than continuity in what is now a long-running project - the 2010 numbers are all in the spreadsheets now. To kick that off, here is the annual chart breaking down how the 2010 EWSL previews compared to each team's actual results (see prior charts for 2009, 2008, 2007, 2006 and 2005).
Key for the chart, by columns:
EWSL: Each team's "projected" 2010 wins by EWSL.
Wins: Actual 2010 wins.
Team Age: Weighted average age of each team's preseason 23-man "roster" weighted by raw EWSL.
2010 WS: Win Shares earned in 2010 by those 23 players, expressed in Wins (WS/3).
W +/-: The number of wins by which 2010 WS exceeded - or fell short of - EWSL. Basically, if EWSL is the expected baseline for each player's performance, this column tells you which teams did better or worse than could be projected from the talent of the 23 players on hand that I included in the preview. Since the main purpose of this exercise is to evaluate how well EWSL fared as a predictor of team performance (as I've noted repeatedly, it's not actually a prediction system, just a fairly rough way of evaluating talent on hand), I've ranked the chart by this column.
Rest: The number of wins (WS/3) earned by players on that team who were not in the preseason previews. Basically, this column tells you how much each team got out of players who weren't on my preseason radar, either because I guessed wrong who would make up the depth chart or because they brought people in by trade, from the minors or elsewhere who ended up being significant contributors. My 2010 EWSL "wins" worked from an assumption that the average team would earn about 13 wins from the rest of the roster, so you have to bear that average in mind when comparing this column to expected results.
Here are the results:
A few notes:
-As usual, EWSL did about what you'd expect: it got half the teams within 5 wins of the results for their rosters, was way, way off on a handful at either end, and didn't really have any way of projecting what teams would add to their preseason depth charts.
-The Reds, Blue Jays, Padres and White Sox easily outstripped every other team in getting more from the players on their preseason depth charts than you'd expect. The Mariners and D-Backs fell the furthest short (EWSL had the Mariners as a first-place team, which is about the largest possible error, and Arizona as a strong second). The Mets, even with some fairly tempered expectations, also fell pretty far short, thanks to getting a lot less than projected from Beltran, Castillo, Francouer and (ugh) Mike Jacobs.
-The Mets were, however, second only to the Giants in finding help from unexpected quarters, in the Mets' case the youth movement led by Ike Davis and the scrap heap brigade led by RA Dickey. The Giants came in almost exactly where EWSL had the 23 guys on their depth chart; their surprising run to World Champions was driven by additions/promotions like Buster Posey, Pat Burrell, Madison Bumgarner, and Santiago Casilla). The A's, for once, were not leaders in getting extra help. The Cubs, White Sox, Yankees and D-Backs got almost nothing from anybody but the people on their preseason depth charts (other than Arizona, this was an unsurprising byproduct of having a roster already full of older established players with a firm grip on their jobs and a settled bench and bullpen - the three oldest teams, the Yankees, Red Sox and Phillies, all relied heavily on the people who started the season with a job).
-MLB-wide, teams earned 1247 Win Shares, or 41.57 per team, from the rest of their rosters. Results year-by-year since I started tracking results at a team level:
2005: 1067 (35.57)
That may partly reflect that I've gotten worse over the years at projecting teams' core rosters, but on the whole, it does indicate at least some sort of rising trend from 2007 on in teams getting slightly more from second-line players, prospects and trade acquisitions than from their Opening Day rosters.
