Everybody is familiar with You Win With People, but not many people are familiar with Hot Line to Victory.
This is a football coaching book written by Woody for prospective football coaches. It was written after the 68 season and covers such topics as game plans, play design, etc.... There are even play charts from the 68 Purdue Game (IIRC it is that game)
In any case, it is a rare book. I purchased a copy for my dad for Christmas this year.
This weekend I found another copy. It is at the half price books on Bethel road. Asking price is $150.00. Not cheap, but it is something die hards should have.
