Hoping to create fantasy league using weekly NFL lineups on DK or FDS platform. Hoping for any ideas or feedback!

I love the concept of fantasy football but would love to build around weekly lineups instead of the traditional fantasy style.

I am hoping to create a league that has weekly incentives along with annual standings/incentives and just using free lineup options on a DK or FDS with payment structure off the platform.

Has anyone done anything like this? Or have any ideas for ways they would go about it or add to it?

Maybe you can already do it somewhere and I’ve missed it but love the concept.

Thanks!
