And you don't necessarily need to have one of each. In late 2007, the Pats used a lot of Meriweather and Sanders as their two true safeties (call them FS if you want) and used Rodney underneath in more of a SS role. It all depends on the offense and the situation. The fact of the matter is, Rodney is no longer equipped to be one of your full-time deep safeties. The Pats may bring him back or bring Tank Williams back to be that underneath guy, but Meriweather is the only true safety right now. The Pats can keep James Sanders, find another like safety in free agency, or go that route in the draft.
