Klecko, a defensive lineman who was an integral part of the New York Jets ``Sack Exchange'' in the early 1980s, and Joe Fields, the Jets all-pro center, tell their stories in this dual ``autobiography,'' written in the third person with sportswriter Greg Logan. The two have much in common. Both are from blue-collar families, and their background translated into a solid work ethic on the Jets. Jets head coach Joe Walton's tirades and defensive lineman Mark Gastineau's spoiled-brat antics made Klecko and Fields's last years with the Jets uncomfortable. Both men played hurt throughout their careers, and Klecko's dismissal at the end of the 1986 season following knee surgery seems unwarranted. Neither was a supporter of the 1987 NFL players' strike, and both crossed the picket lines. They offer thoughtful comments on the strike, which resulted in sharp divisions among the players.
