In a sneak preview of the Season 7 premiere, we see Rick in the immediate aftermath of Negan killing a member of the group. Rick is sporting a noticeable blood spatter on the right side of his face that was not there when last we saw him.
Chances are that means the person who died was on Rick’s right side in the lineup, so either Rosita, Michonne, Abraham, Maggie, Daryl or Glenn is the most likely victim. That’s good news for Sasha, Carl, Eugene and Aaron, who were all on Rick’s left.
When Negan lined up the group, Maggie was immediately to Rick’s right, followed by Abraham, then Michonne. Daryl, Rosita and Glenn were the farthest away.
