Re: What makes a good book to you?
Don't make the protagonist a Cards fan.
I don't know how to explain HOW to do this, but keep the reader guessing, not with weird plot twists that make no sense, but do the unexpected at least.
Championships for MY teams in my lifetime:
Cincinnati Reds - 75, 76, 90
Chicago Blackhawks - 10, 13
University of Kentucky - 78, 96, 98, 12
Cincinnati Bengals - None
Chicago Bulls - 91, 92, 93, 96, 97, 98
