Autodraft help

Footclan assemble (Insert horn sound)…I am embarrassed to have to ask this. I am in a long-term league (12-team, standard) with family who for reasons unknown wants to to an all autodraft this year. I hate this but…#family. I have zero experience with autodraft. Does anyone here have any experience with setting the pre-draft rankings? Should I just use the top 200 provided on this site or ESPN pre-draft ranks (which kinda suck).
