Simmons vs Gladwell - the Ali-Frazier of writers

I don't think there are two writers who I am more engrossed in than author Malcolm Gladwell and ESPN's Bill Simmons.

Gladwell continues to churn out books that promote thought - "The Tipping Point", "Blink" and "Outliers"; Simmons column in ESPN the magazine - 'The Sports Guy' - is first-class reading.
