It’s that time of year folks! With the Chiefs driving deep into the playoffs and focused on a return trip to the Super Bowl, pick up my friend David Smale’s history of the Chiefs franchise in Keys to the Kingdom. You can find it here. And for you basketball fans, get a head start in understanding what bracketology is all about. David also wrote Bracketology: March Madness, with Joe Lunardi – the father of the science of bracketology. Go buy the book now, here!
