We're joined now by New York Times enterprise reporter Alan Schwarz. Best known for his groundbreaking work on football's concussion crisis, he also wrote a terrific history of the role of statistics in baseball, and is a regular recipient of warm holiday greetings from Roger Goodell. Have questions for him about League of Denial, sabermetrics, or just how much of that sweet NFL concussion payout he got? Have at it in the comments below.
UPDATE: Alan has to take off; thanks to him for dropping by.
