Youth coaching
During his tenure at FC Dallas, Snell developed a curriculum that included teaching age-appropriate tactics through small-sided games for ages U7-U11. Snell's philosophy was that the "best train with the best", and created the Premier team format which grouped all of the top players in each age group into one 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 so that 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 house league for FC Dallas players on Sundays. He grew the wildly successful program from 5 teams to over 30 teams to preach the small-sided game's format to all the coaches 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. Snell's training methodology was heavily influenced through TGFU, Constraints Led Approach and Games Based Learning.
