NFL's greatest QBsWith Brett Favre's retirement this week, pundits have debated where the Packer legend belongs on the list of pro football's greatest quarterbacks. The answer is, not in the top 10. It's a tough list, also void of Fran Tarkenton, Dan Fouts, Steve Young, Terry Bradshaw and Y.A. Tittle. •10. Len Dawson: Underrated. Greatest AFL quarterback ever, in a league that sported John Hadl, Daryle Lamonica, George Blanda, Bob Griese, Jack Kemp and Joe Namath. •9. Roger Staubach: The player who most lifted Dallas to America's Team status. •8. Peyton Manning: Will climb higher. Maybe much higher. •7. Tom Brady: Will climb higher. Can he hold off Peyton? •6. Sammy Baugh: NFL's first great passer. •5. Dan Marino: Not every great quarterback can win a Super Bowl. •4. Joe Montana: Played on great teams late, but made the 49ers great early in his career. •3. Otto Graham: Ten seasons, 10 league title games. •2. Johnny Unitas: Defined the position until Elway's prime. •1. John Elway: The total package. Great arm, great feet, great leader.
