that one year on the sidelines, returning to Green Bay in 1935. The Giants wooed him back to start 1936 with them, but he played only six games the entire season, five for the Giants and a final game for the Pittsburgh Pirates, the future Steelers. Hubbard returned to football coaching briefly, serving as head coach of his alma mater Geneva College in 1941 and 1942. He was among the initial class of inductees to the Pro Football Hall of Fame in 1963. In a 1969 poll by the Hall of Fame committee, Hubbard was voted the NFL's greatest tackle of all time. Baseball career Even while Hubbard's football career was going full-force, he began to focus on a second career in baseball officiating. From 1928 onward he spent his football off-season umpiring in minor league baseball. By 1936 Hubbard had been called up to the major leagues, umpiring in the American League from 1936 to 1951, a contemporary with the likes of Yogi Berra. Soon recognized as one of the game's best officials, he was selected to work in the 1938 World Series, followed by Series appearances in 1942, 1946 and 1949. In addition, he umpired in the All-Star Game in 1939, 1944 and 1949, behind the plate for half of the 1939 and 1944 midsummer classics. Hubbard found the then-common practice of officials moving to different positions on the field during a game to be confusing and hampered accuracy when making calls. Applying his football experience to baseball, he devised a system where each official had clearly defined duties and also added an additional official to the crew. This was the foundation on which MLB established new officiating standards in 1952. While he was hunting during the 1951 off-season, a ricocheting pellet from a friend's shotgun blast accidentally struck Hubbard in the right eye. The damage was extensive enough to force his retirement from baseball officiating. However, the American League soon hired him as an assistant supervisor for league officiating crews, and in 1954 he became the top supervisor, a position he would hold until retiring for good in 1969. Final years Never a fan of big cities, Hubbard had moved to Milan, Missouri, in 1944. He left in 1945 but moved back in 1948 for good. Milan was a small town much like his native Keytesville, which is about 50 miles to the south on Missouri Route
