^^ This is why I believe Payton did that crazy move with yanking Brown and shifting Strief over, who apparently hadn't played a snap on that side in years, so suddenly in the middle of a game, with no planning. Payton just couldn't trust Brown with Drew anymore. Zach Strief, whatever people here may think of him or his skill level, Payton knows him, and knows he can trust him. He is a known quantity and Payton knows that Strief gets the "do your job" and "next man up" ethos. It became like a "who do you want in your foxhole" decision.

It's similar to the one or two times when they've put Jimmy Graham out there on defense on a Hail Mary at the end of the game. It's not his position, but at the end of the day, Payton trusts him more than he trusts some backup third string safety, to make a grab or bust a ball up in the end zone.
