a bad reputation both for being unsightly as well as being more hazardous to play on compared to natural turf. The league's requirement for grass fields automatically ruled out the use of domed stadiums since no such stadium capable of accommodating a grass football field existed in the U.S. in 2001 (the only retractable roof stadiums complete at the time were used exclusively for Major League Baseball; the first retractable roof stadium for NFL use was not completed until Reliant Stadium opened for the expansion Houston Texans in 2002). Furthermore, every XFL field was designed identically, with no individual team branding on the field. Each end zone and 50 yard line was decorated with the XFL logo, with the endzones also being painted black. Most of the league's stadiums were football-specific facilities, the only exception being San Francisco's Pacific Bell Park (home of the San Francisco Giants) which was built primarily for baseball, but (unlike many newer baseball-specific stadiums) can accommodate football. Two XFL stadiums (Giants Stadium and Soldier Field) were also then-current NFL stadiums, while two others (Los Angeles Memorial Coliseum and the Liberty Bowl Memorial Stadium) had previously hosted NFL games; the NFL would return to the Coliseum when the Rams returned to Los Angeles in 2016. The remaining fields were in regular use as college football venues at the time. The home team in every stadium was required to occupy the sideline opposite the press box in order to be visible to the television cameras. Due to the odd field dimensions in San Francisco, teams playing there were permitted to occupy the same sideline (a similar arrangement existed in the NFL when the Green Bay Packers played home games at Milwaukee County Stadium and in stadiums previously used by the Chicago Bears, Detroit Lions, Kansas City Chiefs and Minnesota Vikings). The all-grass field stipulation caused the league to skip over several of the country's largest markets, including Houston and Philadelphia, since they lacked a large grass stadium in 2001. In the league's two northernmost markets, Chicago and New York/New Jersey (the latter of which played in Giants Stadium during a brief window in which the stadium's usual artificial turf had been replaced by natural grass), the combination of the all-grass requirement, midwinter playing season and the fact that the XFL followed shortly after the NFL had used both fields for a full season (in Giants Stadium's case,
