BJ Penn, The Guard, Performance Menu, issue 31, August 2007(opens in a new tab)
In his own 2007 technical article, Penn recommends using strikes from the bottom in MMA to create submissions, sweeps or a chance to stand, rather than merely scoring with punches while remaining under an opponent. This is direct evidence of how he adapted jiu-jitsu guard for MMA.

Penn's article presents sit-up guard as a way to close distance and move more safely from the bottom when strikes are allowed, an explicit teaching example rather than a claim that he invented the position.
