The entire time that I was reading their comparisons of Billy Beane, I was waiting for the hammer to drop but it never came. They pumped success but failed to mention that Beane's A's went 226-259 between 2007-2009. Even if the book was all wrapped up in 2009, they still could have at least addressed Beane's 151-172 record between 2007-2008. What happened was once his secrets were published in Moneyball in 2003 and other teams saw how successful you could be with his tips, smart teams immediately copied his basic principles and Beane was no longer able to take advantage of the market inefficiencies he exploited in the early 2000's. It took all of four years for baseball to quite likely overvalue young players while undervaluing older players.
35+ year old guys like Johnny Damon and Vladimir Guerrero could only get one year of guaranteed money while the Indians have to be kicking themselves for signing current DL darlings Travis Hafner and Grady Sizemore to long-term contracts when both players were entering their primes. The overall philosophy of sign young guys to low contracts and avoid signing older players to big money works out in many cases (young guys/low money: Evan Longoria, old guy/lots of money: Jeff Suppan) but there is no guarantee. And sign guys with personal problems and help them deal with them? Paging any team that has tried to work with Milton Bradley.
Overall Soccernomics does have a good list of what to avoid and what not to avoid but I would have labeled the list "Current Trends to Avoid" instead of "Secrets of the Transfer Market". The real list?
- Exploit market inefficiencies and leave your competition in the dust.
