I wasn't saying you were the one who made the suggestion on moving David to safety, but it has been discussed on here.

There isn't any CB who has played his whole career at CB, who has successfully converted to safety.
That's not true. Off the top of my head, Dave Waymer played many years as a mediocre CB and then became a very good safety.
That being said, MM is a CB, he is not physical enough to play safety. Moreover, we need more help at CB than we do at safety, there would be no point in moving your best CB to safety when you have a huge hole at CB.
