USL League One began its inaugural season March 29 with 10 teams. It has plans to expand to 24 teams by 2021, and already has announced future clubs in Harrisburg, Pennsylvania, and Rochester, New York. The closest team to Omaha is in Madison, Wisconsin.

The league is sanctioned at the Division 3 level by the U.S. Soccer Federation, two tiers below Major League Soccer and one below the USL Championship. All of its regular-season and postseason games are broadcast on ESPN+, a subscription-based streaming service.

Green said the league was a “perfect fit” and that if crowd size and sponsorship grow large enough, he would consider moving the team into the USL Championship.

Given its Division 3 sanctioning, League One may sound confusing, but it’s consistent with a naming tradition in the United Kingdom. The United Soccer League rebranded each of its three leagues beginning this season.

In England, the first through fourth divisions are known respectively as the Premier League, the Championship, League One and League Two. Similarly, the top U.S. league is MLS, followed by USL Championship, USL League One and USL League Two.
