Weeb Ewbank's sphere of influence

ESPN celebrates the 100th anniversary of Vince Lombardi's birth with the "Greatest Coaches in NFL History" series, saluting the finest innovators, motivators, tacticians, teachers and champions ever to stalk the sidelines. Follow along as we reveal our list of the top 20 coaches of all time and document the lineage of the league's most influential coaching trees.

The Weeb Ewbank branch of the Paul Brown coaching tree is documented in the chart below, followed by a feature on Ewbank and short biographies of his many disciples.
