It's not the system guys, so don't blame Canales. Play calling may be iffy at times, but the concepts are solid. WRs were open a lot yesterday, go back and look. I counted two tight window/precision type of throws required of Bryce, even then they weren't overly difficult by NFL standards.. The rest of the time, guys were open. In the NFL when WRs are open, QBs are expected to hit them. It's not even debatable.
I've been watching Mendoza put the ball in insanely tight windows all season....down the field too. In the Oregon game, he had two throws that, if not utterly PERFECT, could not have been completed. They were flawless throws. If a college QB can do this, it's not asking too much of a NFL QB wrapping up year 3 to do it.
