Prince Fielder comparables

By Tangotiger, 02:29 PM

I looked at the last 10 firstbaseman (born not later than 1973) to have had at least 10 WAR from age 25-27.  These 10 players averaged 13.8 WAR, right in line with Prince’s 14:

WAR    Born Player
17.7    1973    Todd Helton
10.9    1973    Mike Sweeney
14.8    1970    Jim Thome
19.4    1968    Jeff Bagwell
18.3    1968    Frank Thomas
17.3    1964    Will Clark
13.2    1964    Rafael Palmeiro
15.2    1963    Fred McGriff
10.9    1963    Mark McGwire
10.1    1963    Cecil Fielder

I got a chuckle at #10 on the list.

Anyway, how did these guys do over the next 9 seasons?  I added a column to the above chart called “WAR9”, which is the number of WAR from age 28-36:

WAR9    WAR    Born    Player
 37.2     17.7    1973    Todd Helton
 10.6     10.9    1973    Mike Sweeney
 40.5     14.8    1970    Jim Thome
 50.6     19.4    1968    Jeff Bagwell
 33.9     18.3    1968    Frank Thomas
 26.0     17.3    1964    Will Clark
 41.9     13.2    1964    Rafael Palmeiro
 23.1     15.2    1963    Fred McGriff
 43.9     10.9    1963    Mark McGwire
 4.8     10.1    1963    Cecil Fielder

The average is 31 WAR.  If we start a player at 4.8 WAR, and gradually accelerate his aging, we get this kind of aging chart, along with the cost per win (starting at 5MM$ per win, and increasing at 5% each year):

WAR      $perW      Value 
 4.8      
$5.00      $24.0 
 4.7      
$5.25      $24.7 
 4.5      
$5.51      $24.8 
 4.2      
$5.79      $24.3 
 3.8      
$6.08      $23.1 
 3.3      
$6.38      $21.1 
 2.7      
$6.70      $18.1 
 2.0      
$7.04      $14.1 
 1.2      
$7.39      $8.9

The total comes in at 9 years, 183MM$.

If we take out Cecil Fielder (for whatever reason you want), the other 9 comps average out 34.2 wins, and that would work out to 201MM$.

So, we can create some reasonable scenario where the overpay is some 13MM$ to 33MM$, rather than the 50-100MM$ being discussed.
