Every year since 1998 I've been keeping track of team's "core ages", which I classify as their
keeper list plus their 1st or 1st & 2nd round picks.  Below is this year's edition, also showing
the last 5 years worth of data.  

The Pitbulls repeat as the team with the youngest core, and the Termites repeat as the team
with the oldest core.  The Piazza's leaped to the middle, shaving off 2.5 years to their core,
while the Moshers added 2.5 years to their core.
