"Stumbling On Wins" is actually by both Dave Berri (of The Wages of Wins Journal) and Martin Schmidt -- a book where "two economists expose the pitfalls on the road to victory in professional sports" ... or so the tag-line goes.
Right now, on Truth About It.net, there's a contest where you can win one of two copies of the book (and some Wizards swag).
Basically you just have to answer some trivia about Wizards/Bullets franchise history and I will select the winners from the pool of entrants. Good luck.
