Romanowski, with 16 seasons in pro football, has written an NFL Dr. Jeykll and Mr. Hyde -- a tale about a football player who wants to maim his opponents but carry on a normal family life away from the game. "It will be a story of a guy most people think is crazy, the guy who is out on the field being a warrior and the gladiator, the guy who would do anything to be the best he could be," he said when beginning the book. Romo talks plenty of smack about his own Dr. Jekyll, the linebacker who spit in the face of wide receiver J. J. Stokes; punched out his own Raiders teammate Marcus Williams; broke the jaw of Giants quarterback Kerry Collins; and was fined hundreds of thousands of dollars by the NFL. He is the most hated and dirtiest player in the NFL, but that's not where the juiciest elements come it. Romanowski has been a central figure in the BALCO case that has attracted national attention to the increasingly controversial subject of sports supplements, and he has promised to reaveal everything -- coming completely clean -- about BALCO, the designer steroid THG, and the diet pill phentermine, which is now banned by the NFL because of Romanowski, who was indicted (and acquitted) on four felony counts of using the drug.

But in addition to being controversial, Romo intends his book to be educational, too, including lessons learned from some of the biggest coaching names in the game. Romo is a full-throttle inside look at football, no one who has ever cared about the sport can afford to ignore it.
