The league deliberately avoided placing teams in stadiums with artificial turf, which at the time had 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.
