Dynasty League w/ deep minors seeking replacement

This is a 16-team, H2H free Yahoo league with 30 man rosters and 30 man minors rosters.  One manager is leaving due to personal reasons and I'm looking to replace him.  This is an active league and you need to know the minors + need to enjoy prospecting.  The team is in 5th place right now so this isn't a rebuilding project - you are inheriting a winning team.  Roster below.
