Xavier Rhodes is a more likely conversion, if he ends up playing for us at all this year. He is a bit older, has the size and his style of play fits the position well and past experience as a box safety. It was even originally speculated when he was coming out of college, that he would make this conversion later in his career:
"However, Rhodes does have some experience lining up n the box as a safety, and a possible move to the safety position later in his career is possible."
