The Spring League (TSL) was an American football developmental league and scouting event that played from 2017 to 2021 and was founded by Brian Woods. Aimed at professional athletes but not paying a salary or expenses, the league's goal was to "serve as an instructional league and showcase for professional football talent".
For 2019, The Spring League tested rules for the XFL. Seen here is the later implemented XFL kickoff formation.
The XFL was a professional American football minor league consisting of eight teams located across the United States in mid-sized to major markets. It is now one of the two-component conferences of the United Football League (UFL), along with the United States Football League (USFL). The XFL league headquarters were in Arlington, Texas.
