The goal is for lost souls at major sporting events to be reconciled to and know God (John 17:3).
The means of the goal is explained here:
The fan is presented with an opportunity to respond to the Gospel which includes asking the evangelist questions and being ministered to in the moment based on their respective place with the Lord.
Thus the SFOI evangelist both preaches the Gospel and ministers to the fans as they respond and hopefully is able to refer the fans to a Bible teaching church for discipleship. [Acts 2:38, 3:19, 5:31, 8:22, 17:30, 20:21, 26:20; 2 Cor. 7:10; 2 Peter 3:9; Rev. 3:19]
The fans hear the Gospel as they participate in pre-game events either at the respective venue or at a fanfest** perhaps located in the downtown area of the host city. In other words the fans are not inside the venue when they hear the Gospel.
The Gospel is communicated via preaching, distributing literature and individual conversations. All hearers are called to repent and believe the Gospel if they don’t and are edified and ministered to if they do believe It. All vision and mission statements, organizational and training efforts are designed to lead to fans hearing the Gospel at major sporting events.
The pictures you see on the Photo page show the locale and interactions taking place.
**Fanfest is a word describing events hosted by the particular event or host city that are intended to attract fans whether they are attending the event or not. At the Super Bowl for instance they have the NFL Experience and two years ago in San Francisco the city hosted the Super Bowl City.
