Oakland's O.co Coliseum is the only remaining stadium shared by a Major League Baseball team and an NFL team. To this day, early season Raiders games feature the distinctive infield cutout that conjures up memories of a bygone era in sports -- when football teams played home games in stadiums designed primarily for baseball. The Raiders moved into the Coliseum in 1966 and played there until their move to Los Angeles following the 1981 season. When the team moved back to Oakland, the Raiders again called the Coliseum home. (Aaron Kehoe/Associated Press)

Buffalo Bills defensive back Nate Odomes (37) returns an interception and San Francisco 49ers tight end Jamie Williams attempts to make the tackle in a game played on Sept. 12, 1992.

Candlestick has hosted an astonishing eight NFC Championship games. (Al Golub/Associated Press)

Houston Oilers fans enjoy a 58-14 victory over the Cleveland Browns at the Astrodome on Dec. 9, 1990.

However, the Falcons were once an outdoor team, playing in a stadium shared with baseball's Atlanta Braves. The Falcons played at Atlanta-Fulton County Stadium from their inaugural season of 1966 through 1991. (Judy Ondrey/Associated Press)

An aerial view of Cleveland Municipal Stadium as it looked in 1994. "The Mistake by the Lake" was home to the Browns from 1946 until the team went on a three-year hiatus following the 1995 season. The Browns, however, weren't the first NFL team to call the stadium home. The Cleveland Rams joined the NFL in 1937 and called the stadium home until 1945 when -- following a 15-14 win over the Washington Redskins in the NFL Championship game held at Cleveland Municipal Stadium -- the franchise moved to Los Angeles. The Browns made the place famous first for an amazing run of championships from 1946 through 1955, and then an epic series of playoff misfortunes in the 1980s. (Mark Duncan/Associated Press)

Naming football teams after the local baseball team was a common practice at the time (ie. New York Football Giants). (National Football League)
