Randy Couture on sleeping before fights

Jay Glazer in this UFC roundtable with legends speaks with Randy Couture before about how he took a nap before his fight with Mark Coleman. Couture makes an interesting point about how conserving energy, relaxing, and "unplugging" can be a great way to save all your force for fighting and not waste any mental and physical energy beforehand with nerves and anxiety and overthinking:

We get there so early, three hours, we were there early. Sit there in a little room. You've got to relax and unplug; if you're keyed up that early you're spending energy you're going to need when you have to walk out there. You learn to unplug.
