One of my many objectives as a collector is to obtain an autograph from every player that played for a Sox playoff team since 1959.  This includes ALL players that played for the teams in those years, not just those on the postseason rosters.  You can view my progress here:

As you'll see once you click the link, I've completed the 2005 and 2000 rosters!  The last autos I obtained for those collections were Jeff Bajenaru and Lorenzo Barcelo, respectively.  I hope to complete 2008 and 1993 very soon.
