In the video they show POB throwing twice and the other QBS were only shown throwing once. However Gebbia and Martinez were also shown handing off. Using the logic of some on this board lately. This means that POB is the only one that can pass, but he does not know how to hand off. PLUS the only pass that we saw completed was POBs. Although the others showed them passing but not whether it was completed. So they must not have been.
