Tyrann Mathieu and Saints to re-visit talks

He’s not a FS. That’s pretty much the only secondary position I’m confident he won’t be playing. I think he backs up the CB spots, and perhaps in 2023 plays nickel of CJGJ leaves or SS if Mayes fails.
Then it's weird to spend such a high pick on someone who has zero chance in starting right?

If we drafted him to play backup CB and to potentially replace someone IF they leave, that seems ridiculous for such a high pick.
