I don't think you understand or appreciate "pocket passing."
It's just a pass play. Quarterback drops back, receivers go out, and the more time they have, chances are they get deeper and/or more open. If a QB can hold his ground one extra second, good things can happen.
If the pocket is collapsing, he can scramble. And because it's a pass play, an athletic QB can take advantage of the big cushion of green that calling a pocket pass created.
That's not "swimming upstream." It's just good football. And it looks like our freshman QB is good at all phases.
I would have called a few more QB draws myself, but Scott Frost was the highly coveted offensive guru, not me. Or you.
