At left, Roosevelt Leaks when he played fullback in Texas' triple option offense. For a discussion of the faceguard on his helmet see the video below.
I'm not sure who is playing quarterback in this picture. It would be too easy to Google that information so I'll take a guess and say James Street.
BTW: in the video I may not have been clear about where Donald Rumsfeld played lightweight football. It was at Princeton, not Columbia.
