You can have your own player on the teams. The guys get drafted & everything. They progress their players each week as well. You can watch on Eleven Sports or FTFNext on twitch. & they have previous games on their SimulationFL youtube channel.
The championship game happened last week but they also have SFLm, a minor league for players that want to jump in & play, & potentially build up a "college" type player to be drafted in the majors. 14 seasons strong. Get involved if you're not already. It's good stuff.
