No matter what you might think is the mostexcitingpart of the game -- a dramatic catch, a punt returned sixty yards for a touchdown -- most people agree that the power of football is in the play-by-play running game. Agile, quick, but most of all powerful, football running backs have the onerous, and sometimes painful, task of moving the ball forward on the ground -- sometimes only inches, sometimes a few yards, and sometimes, with a little luck, they see daylight and scamper into the end zone. It is a rule of thumb that good teams establish the running game first, before they can begin to be confident that their passing game will succeed. And it is on the running back -- the workhorse of the team -- where that responsibility falls.As he did with quarterbacks in his acclaimed bookQuarterbacks,George Sullivan here profiles eighteen of the greatest running backs of all time. From Jim Thorpe to Terrell Davis, each brief profile, accompanied by dramatic full color and black-and-white photographs, brings that star to life and leaves no doubt as to why he was considered great. Whether he had slippery moves that allowed him to avoid tackles or brute force that powered him through the line, the ultimate fact is that he got the job done.
