The Author
 
The Master Defense by Bob Troppman was first introduced in the late 1960's when it was published by Parker Publishing. 

The Master Defense is a comprehensive defensive scheme that is suitable for any level of football. Through its system of numbering fronts and "coloring" coverages, The Master Defense makes it possible to present virtually any "look" to an offense without changing the basic concepts and terminology.

An "out-of-print" publication, The Master Defense returned to life as an eBook in 2001, and includes 100 plus pages that explain and illustrate the concepts that make up the Master Defense in detail.
