Talk of the best-ever teams starts with a pair of New York Yankee clubs--the 1927 "Murderers Row" lineup featuring Babe Ruth and Lou Gehrig, and the 1961 group led by sluggers Mickey Mantle and Roger Maris.
Without a Ruth, DiMaggio or Mantle among them - no certain Hall of Famers and no one even elected to start in the All-Star game this season - these Yankees posted a .714 winning percentage, the best in the majors since their Murderers' Row club of 1927.
