In 1994, to honor the NFL's 75th Anniversary, teams were allowed to wear modern versions of their old uniform styles. However, the designs varied widely in their accuracy: While no attempt was made to simulate obsolete leather helmets which were phased out in the 1950s, teams simulating uniforms from the era of leather headgear simply removed all decals and striping from their regular hard-shell helmets. A rule imposed by the AFL–NFL merger in 1970 adopted the AFL's policy of all jerseys displaying the player's last name on the back side. This practice was not part of the NFL officially until after the merger, but to keep consistency with current rules, the names were placed on the back side of all throwback jerseys. In most instances the fonts and typestyles used were only approximate matches at best. The Arizona Cardinals, Chicago Bears and Pittsburgh Steelers wore reproductions of uniforms that pre-dated large numerals on the front of jerseys, so instead smaller numerals were worn on the right shoulder. The Dallas Cowboys and Buffalo Bills received some criticism for their portrayal of their throwbacks. The Cowboys wore their early 1960s uniforms with their current helmet, while the Bills wore their then-current uniforms with the old "standing buffalo" logo in white on their red helmets, in place of the current blue "charging buffalo" logo. Later that season, the Cowboys used the "double-star" uniform, which could be considered an updated version of the 1960s jerseys. Ironically, both teams have since adopted these throwbacks more accurately as alternates, with Dallas now using the original, plain star helmet and Buffalo using the original red "standing buffalo" helmet on white background, as well as wearing the AFL-era jerseys as opposed to the Jim Kelly/Marv Levy-era jerseys (the two jerseys have few noticeable differences other than sleeve stripes, which were present on the 1960s jerseys but not on the 1990s ones). The Bills adopted 1975-era throwbacks, with white helmets, as their main uniform in 2011. The New York Jets also received similar criticism for using their throwback logo on their then-current green helmets; when they adopted the throwback design full-time in 1998, they also went back to their original-style white helmets. The Bills and Cowboys did the same when they adopted their retro unis. The Miami Dolphins, New Orleans Saints, Seattle Seahawks,
