It wasn’t the “Thrilla in Manila,” but a bout between two Harvard heavyweights grabbed headlines this summer nonetheless. In one corner, you had Clayton Christensen, the dean of disruption, who slammed HBX for being conventional and vulnerable. Across the ring, he faced off with Michael Porter, the father of the five forces, who stressed a steady strategy over Christensen’s Darwinian upheaval. In the end, the media scored their New York Times dust up as a draw, with neither landing a Ronda Rousey right or a Shawn Michaels superkick.
