I don't know the first thing about how hard it would be to program a game like this but it is a solid idea that I think many people would be interested in. I don't think you could make a fortune but if you were to set up a Patreon account and provide weekly status updates and post your idea at a number of sports related sites I'm guessing you could get a good number of people to pledge to help support you while you made the game. Many of those same Patreon supporters would also most likely be interested in playtesting for you once the project got that far.
