Anyone else heard this one before? Pretty funny and shrewd. TLDR: In 1999 as OU's OC, Leach created a fake "script" of OUs first few plays and placed it on the field during warmups before the game. It was picked up by a UT assistant and taken directly to the DC where they assumed it was real. The initial results were about what you would expect but once UT figured it out, they ended up winning the game.
