Re: Gamecock documentary?
There's a great VHS from the late 1980s called "Gamecock Glory" that highlighted a bunch of old games, spent a lot of time in the George Rogers era, and 1984.... I think it ended in the Todd Ellis era. Unfortunately for you, theres a new "Gamecock Glory" book about our championship baseball teams, so any google searches will probably take you to that.
There is 1 more video I know of that was made in the mid 1990s called something like, "100 Years of Gamecock Football" or something to that effect.... That is more a historical video with less game footage and more pictures and interviews....
