I didn't see him making mistakes that killed drives. I saw OTHER PEOPLE making mistakes.

Take the snap over his head. They had started deep in their end and picked up a 1D or two. The drive had a feel of momentum building.

Then the ball goes over his head and they're at the 2. How is that drive his fault?

Or the one where the young RB fumbled it away nearing the RZ on another nice, sustained drive.

Those are not Mannion's errors. Meanwhile he made throws, never turned it over, and engaged the young receivers.

I dunno what you expect from a BUP QB playing with scrubs in a PS game.
