I want to put together the 2020 season with all the new players and latest changes to rosters. Brand new to this, so I need a little direction. How/Where do I go to start modding the rosters. I see there are some guys on here that already have the logos and endzone artwork and player pics. Someone give me some insight on how to begin and I'll be off to the races and modding at warp speed. Just need a kick in the pants. Thanks!

I am pretty new as well...have played under the hood only with play creation thus far. I can point you though, to the mod section of the forum where th best starting place is. I can also suggest as a very first step, downloading the json/ csv file converter which is the top post I believe there, and will be needed to delve into rosters.
Good luck!

That's the link where Tigerman has been working on his roster he provided for PF20.
