I would like to go through this file and tweak some of the overall ratings I disagree with. The file is pretty self explanatory, but I'm noticing that the overall in the .json file is very different from the overall in the game. Perhaps this has been addressed somewhere but I couldn't find it.
For instance:
json file:{"Id":10343,"RefId":"10343","Ovr":63,"Sea":1967,"Rook":1967,"First":"George","Last":"Goeddeke","Team":"13","Coll":"Notre Dame","DOB":"7/29/1945","Hgt":75,"Wgt":253,"Pos":"G"},

but in game shows up as Overall 79?:15237,67,George,Goeddeke,Notre Dame,22,0,75,253,0,0,0,0,0,False,,,0,0,G,G,N/A,0,False,,79

When players are imported from the historical file the game uses their OVR rating to generate the rest, but there is randomness in there. So depending on rolls they could come out much higher or much lower than expected.

In the .json files, there are many players over 100..I think Peyton Manning's 125 is the highest. Is this done to ensure, even with the rolls, a high rating?

Also, in the settings, there is an "Import draft from History" tab. If this is checked, how is it different from loading the HistoricalPlayerData.json file league creation?

Dumb Question from Newbie:

How and where to get actual 2019 NFL rosters?

The high OVR like 125 is to try and make sure they get higher rolls for historical purposes.

The import draft from history checkbox uses the historical file to generate correct draft classes for that year as long as the year is in the historicalplayerdata file.

The game comes with some rosters and there is a mod if you want to start a league with a file that you can tweak first.

I was just trying to figure out why many of the historical players aren't that relevant...the fictional players overshadow them. I believe I have the hang of how their overall rating has been calculated and I see the problem. ( I think )

I'm guessing the game uses this when creating fictional players....but after sifting through the historical player file, I'm going to guess the average rating is closer to 60 for the all the historical players. About half the file are players rated 60 and below. It isn't necessarily wrong....it is just using an entirely different scale. I'm thinking if i adjust MIN and AVG for each position, that will change the distribution of fictional player ratings to be more in line with the historical players. Does this sound right?

All that screen does it change the OVR calculation. The individual ratings aren't affected. If fictional players are all coming in with higher OVR, then they're also being created with higher individual ratings than the historical ones. In which case I probably need to adjust the historical import and make sure the ratings are in line. If you identify specific ratings that are off let me know as that will point me in the right direction on tweaks to make.
