As Sports Illustrated's pro football genius-in-residence, Paul Zimmerman ("Dr Z") has established himself as the presiding dean of America's pro football writers. Now, critics, sports writers and fans across America are cheering The NEW Thinking Man's Guide to Pro Football as the worthy heir to Zimmerman's 1971 classic The Thinking Man's Guide to Pro Football, which Howard Cosell called "the best book of its kind I've ever read." Far more than a revision, The NEW Thinking Man's Guide to Pro Football is virtually a brand-new book (in 1984) prompted by, as Zimmerman writes in his introduction, "a whole new generation of players and coaches (who have) given rise to a new set of reflections about a world that is ever changing." Zimmerman examines positions, tactics, the great players and moments of peak performance, football scouting, broadcasting, minor leagues, the rule changes of the pst decade and how they have inspired new playing stategies (crisply illustrated with diagrams). And with characteristic verve, insight and no-nonsense prose, Zimmerman pays close attention to the effect of football''s pounding nose-to-nose competition on the everyday player's personality.
