Every year since 1998 I've kept track of a team's core "age" (the keeper
list + 1st or 1st/2nd round picks).  Here's them all, updated to the 2000
season.  The youngest team is still the Sacramento Fish, who aged 0.3 years
from 1999.  The oldest, by almost 8 years over the Fish, is the venerable 
Seattle Moshers, whose 1st round draft pick is *still* older than the average 
Fish.  The Mechan Syndicate are in a youth movement of their own, shaving off 
over a year in age every season.
