Working on a book about the 2009 New Orleans Saints and their Super Bowl run. I've interviewed a number of players, coaches, press and members of the front office and compiled a lot of great stories along the way. What I'm having trouble with at the moment is knowing when it's a finished piece. There is always someone else to interview and another story to add, so when do I stop and put a bow on it? I was considering trying to get the book done on the 15th anniversary of that Super Bowl, but that is in February, so no chance that happens. Any feedback is welcome.
