The Cardinals have been shuttling homegrown players to St. Louis with an increasing regularity. - Scott Rovak-USA TODAY Sports
The Cardinals pledged to rely more heavily on player development back in 2007 and, now in 2013, they have been recognized as having the industry's best farm system. That's great and all, but have their advancements translated into more Wins at the major league level?
In October 2007, Bill Dewitt fired Walt Jocketty less than a year after the organization had won its tenth World Series championship. To help you revisit that time, here's a quote from Dewitt addressing Jocketty's sudden dismissal (found in Nate Latsch's MLB.com article):
"I think that we had a little different philosophy and vision with respect to some baseball issues," DeWitt said. "There was clearly tension that was reported widely, not only locally but nationally in the organization. While I've said on several occasions that tension is in every organization, I do think it got to the point with the Cardinals that it was counter-productive. We couldn't achieve our objectives given what was going on inside the organization."
Jocketty took umbrage at the 2006 promotion of Jeff Luhnow, who had been head of amateur scouting, to a position that oversees both scouting and player development. The move came at the expense of Bruce Manno, one of Jocketty's aides.
As noted by Derrick Goold, the Cardinals highest Baseball America farm system ranking between 2000 and 2007 was just twenty-one. Six years later, that's certainly part of what colors our satisfaction in having the industry's number one ranked system here in 2013. Luhnow is responsible for much of this, of course, since he remained in charge of drafts until 2011. Over time, Luhnow's presence became a symbol of the organization's willingness to incorporate more advanced metrics into the decision making process. And so now that the Cardinals' player development efforts have earned the highest praise from third party outlets, it also represents a validation for the more sabermetrically inclined corners of the organization and/or fan base.
This all got me thinking. Would the numbers support popular sentiment that the Cardinals have relied more heavily on homegrown players? To answer this question, I simply counted the Cardinals' total Wins Above Replacement (WAR) and compared it to their drafted WAR, or Wins produced by internally developed players. I used Fangraphs' version of WAR for position players and Baseball-Reference's version of WAR for pitchers. I chose B-R's version of WAR for pitchers because it incorporates actual runs allowed into its formula, so some have argued that it more accurately reflects the value teams actually received from their pitchers rather than the value they should have received based on pitchers' individual performances. Read all about the differences between these two types of WAR in the Fangraphs glossary.
In general, players were considered homegrown if they made their professional debut with the Cardinals. Therefore, Adam Wainwright and David Freese are included in these WAR totals despite being drafted by the Braves and Padres, respectively. It makes sense to credit the Cardinals for having raised them since they never appeared above double-A for their previous teams. Besides, the Cardinals were savvy enough to acquire them in the first place.
