Gene disagreed with you.
HandjoCommando doesn't know what the F he's talking about yet again. A Fair Catch signal is when you're hand an arm are put straight up above your head and wained side-to-side. At a minimum, the side-to-side signal must be made above the shoulder. In this case, PSU returner's arm never goes above his shoulder AND it most certainly was never waived side-to-side. Ridiculous call especially given that it wasn't made during the play and created out of thin air at the Oregon Coach's request.
