PRO: Bestselling author of such books as Moneyball and Liar's Poker—considered a must-read for anyone heading into finance—who in 2006 released his critically acclaimed book The Blind Side: Evolution of a Game.
CON: His narrow focus on finance and sports fosters a niche "alpha male" fanbase, limiting his appeal to a broader audience.
