In the 1950s the best franchise in Pro Football were the Cleveland Browns, they won five NFL Championships. And a few All American Football Conference Championships as well and even beat the defending NFL Champion the Philadelphia Eagles in the late 1940s, when the AAFC was considered a joke. The Cleveland Browns weren't a joke, the weren't the best team in Minor League Football but the best team in Pro Football period but the two other dominant franchises in the National Football League in this period. Were the Chicago Bears and I hate to say it as a Washington Redskins fan, the New York Giants they met for the NFL Championship 3-4 times in this decade, the Baltimore Colts. With Head Coach Weeb Ewbank, QB Johnny Unitas, HB Lenny Moore and many others came on late in this decade and won back to back NFL Championships in the late 1950s. But the Bears were the best of the West in the NFL and the Giants were one of the best in the East, right there with the Browns. So its natural that the Bears and Giants would be playing for the NFL Championship on a regular basis in the 1950s.
When you think of the Giants of the 1950s, you really only need to think of two people, Vince Lombardi who then was the Giants Offensive Coordinator. And Tom Landry who then was the Giants Defensive Coordinator, both who of course would go on to be Hall of Famers as Head Coaches with the. Green Bay Packers and Dallas Cowboys respectively, Jim Howell the Giants Head Coach really didn't have to do much of anything with Lombardi running the offense and Landry running the defense but step in when things weren't going well I guess. Which didn't happen very often, Lombardi put together the offensive game plan and the offensive lineup and Landry did the same thing for the defense. And Lombardi had QB Charlie Connerly, HB Frank Gifford, FB Alex Webster, WR Tobin Rote and a solid Offensive Line and Landry had DT Andy Robostelli, DT Rosey Greer and many others on defense.
Even though the Giants would go onto winning two other Eastern Conference Championships in this decade. 1956 was the last NFL Championship they would win until 1986, they lost to the Colts in 1958 and 59, lost to the Packers in 1962 and the Bears in 1963 but they were in contention to the end of the early 1960s. The Bears would win another NFL Championship beating the Giants in 1963 but this was towards the end of the era that the Giants and Bears dominated the NFL.
