WATCH: The staredown between Holly Holm and Valentina Shevchenko was almost uncomfortably long

Many fight fans believe that the outcome of a fight can often be foreshadowed by the staredown that takes place after the weigh-ins.

Some fighters are too emotionally involved, some look drawn out and most try to get that little bit of advantage in the mental warfare. Holly Holm's composure when squaring off with opponents is well known and that got right under Ronda Rousey's skin ahead of their UFC women's bantamweight title fight last November, when 'Rowdy' let emotion get the better of her the night before she lost her belt and undefeated record. https://www.youtube.com/watch?v=2UOHe7fC_i0 We saw a similar resolution from 'The Preacher's Daughter' on Friday night, when she came face to face with Valentina Shevchenko on the eve of their UFC on FOX 20 headliner. But she was met with an unwavering Shevchenko and 20 seconds passed with neither fighter willing to blink in the battle to appear unflinching.
