Historical DB Formatting

[thakfu]

I've been looking to extend the historical DB for my league and I had a question....

I've been referencing Brooks' guide: viewtopic.php?f=254&t=27590

However, what I did notice is running QBs are actually flagged in the json file with "Flg":"1".
{"Id":8383,"RefId":"8383","Ovr":108,"Sea":1988,"Rook":1983,"First":"John","Last":"Elway","Team":"13","Coll":"Stanford","DOB":"6/28/1960","Hgt":75,"Wgt":215,"Pos":"QB","Flg":"1"}

This doesn't appear on the above guide. Is there any other data that can be added to the historical JSON? Like perhaps player traits or attributes? Individual ratings? Uniform numbers?

Thanks!
