One video is a no-frills overhead view of a professional volleyball match, a muted 30 seconds of an intense rally between teams USA and Japan during the 2013 USA Volleyball Cup.
The clip is labeled "Juliann Faucette" — Johnson's maiden name — "Ends Rally." Her face is a small blur on the screen, identifiable only by a stark white number 19 on her navy jersey, but she's tall and lithe and ruthless as she sprints to the net and hits the ball over — hard.
Another YouTube hit is an acoustic cover of David Guetta and Sia's popular dance single, "Titanium." The video opens on a young woman who begins to sing, her voice following the peaks and valleys of Sia's original vocals. She snaps out of her musical reverie as the last note fades out, looking straight into the camera with a grin.
This video was posted by one Juliann Johnson — and yes, it's the same Juliann Johnson who dominates international volleyball courts without batting an eye.
