Welcome to the fourth season of Build-A-Blacklist.  Theme details are below, but here's how this will work:

After each season, 10 new players will be added to the permanent blacklist, as follows:
AL MVP
NL MVP
AL Cy Young
NL Cy Young
AL Fireman
NL Fireman
League HR Champion (ties broken by highest AVG first, then RBI)
League SB Champion (ties broken by highest AVG first, then RBI)
League AVG Champion (ties broken by highest HR first, then RBI)
And the tenth man will be chosen by the owner of the World Series-losing team.  He gets to blacklist one player from his opponent's roster who had a salary greater than $1M.  A small measure of revenge.

If the same player wins both leagues' MVP or Cy Young or Fireman awards in the same season, then I'll look at the second place finisher in each league and blacklist the one whose team had the most regular season wins.  If a player wins the MVP but is also the league HR, SB, or AVG champ, then second place in the HR, SB, or AVG race will be added to the blacklist.  No matter what, 10 new players will be blacklisted after each season.  Once a player is blacklisted, ALL seasons of that player are blacklisted and may never be used again.  Details below...
