I once heard the Tennessee football coach tell his team to play with "Relentless Abandonment".
I spent a great deal of time looking up the definitions of these words and trying to determine their meanings (other than the obvious ones that come to mind).
The best I could come up with is this:
Play the game like your a "possessed madman" willing to sacrifice your life for the victory!
