In the days and weeks leading up to training camp, we will continue our series, breaking down the 49ers offense from last season. The previous breakdown was about passing concepts for Ricky Pearsall and Jacob Cowing to take advantage of. This breakdown is about five passing concepts run to perfection by Brock Purdy.
Arches/Return
Generally, the arches concept pairs an angle route from the backfield (run by Jordan Mason) with a shallow drag from the outside receiver (run by Brandon Aiyuk). Shanahan adds a return route from Kyle Juszczyk as his variation to the old-school concept.
