Clarifying right-backs

Alright, I'm considering right-backs like Molina, Montiel, and sometimes Juan Foyth, who can play both CB and RB. Nehuen Perez and Facundo Maffeo are options too, along with Leonardo Godoy. It seems like this is a deep position. I want to avoid any misinformation, so I'll keep it general. Also, I'm curious about how I can help—do you need an article summary or post copy? Let me know!
