Lombardi's WOULD actually be worth reading. He was a thinker, an innovtor and he was a powerful force in a variety of arenas for many years. Plus, he's iconic. Thus, his autobiography probably has some educationa value. Plus, it'd just be fascinating to see how he ticked. ;)
I'm not sure he ever wrote an autobio, but there's a bio by David Maraniss called "When Pride Still Mattered."
