The Arena Football League (AFL) was a professional indoor American football league that operated from 1987 until 2019. It featured a unique format, with teams playing on a smaller field, typically inside arenas, which allowed for a fast-paced and high-scoring game. The league aimed to provide an exciting alternative to traditional outdoor football, attracting fans with its dynamic style and entertainment value. Teams in the AFL were known for their high-scoring games, often featuring scores in the 50s or 60s. The league had a playoff system culminating in the ArenaBowl, where the top teams competed for the championship. The AFL helped popularize indoor football and influenced the development of similar leagues.
