Grambling St. (LA) Data Questions

I would appreciate any answers to these Data Questions

General Data Questions or Missing/Incomplete Data:

1 Missing games for 1948 and earlier

I don't have all Coach Robinsons games and can't make the totals add up without adding "unknown" games

I believe many games are missing from 1928-1940
