North American Soccer League: The North American Soccer League (NASL) is a professional men's soccer league with eight teams: six in the United States, one in Canada and one in Puerto Rico.  It is sanctioned by the United States Soccer Federation (U.S. Soccer) as a Division II league in the United States soccer league system, under Major League Soccer (MLS) and alongside United Soccer League (formerly USL Pro).  It is headquartered in New York City.

Major Indoor Soccer League (2008–14): The Major Indoor Soccer League (MISL), originally known as the National Indoor Soccer League, was a professional indoor soccer league which began play in 2008.  It was the third league to be known as the Major Indoor Soccer League after the MISL I and MISL II.  The MISL name is arguably the most recognizable name in indoor soccer due to its history dating back to 1978.  The league name and assets are currently owned by the United Soccer Leagues.  The departure of six teams which joined the Professional Arena Soccer League (now the Major Arena Soccer League) after the 2013–14 season effectively ended the MISL.

Mark Snell: Mark Snell is a retired American soccer goalkeeper who played professionally in the North American Soccer League and the Major Indoor Soccer League.  He coached in the FC Dallas youth system for eight years, and is widely considered one of the top youth development coaches in the country for Zone 1 (6-12 yr olds).  At FC Dallas he developed the curriculum that included teaching age appropriate tactics through small sided games.  His philosophy was that the "best train with the best" and created the Premier team format grouping all the top players in each age group onto a team.  Initially, players of all levels were scattered across many teams within each age group.  Snell felt the best development model was having teams made up of "like" talent.  That way training would be competitive for all teams regardless of talent level.  He also authored and managed the street soccer based "FCD LIGA" which was a 3v3/4v4 in house league on Sundays.  He grew the wildly successful program from 5 teams to over 30 teams to preach the small sided games format as the best player development tool.  He also organized and managed the FC Dallas Development League which hosted the top U9 teams in the Dallas Metroplex.
