Bob Sanders
Him and Ryan Clark are two of the top tier crash out safeties in modern football. ZERO sense of self preservation.
That said, Ed.
Prime made the passing game dangerous on one side of the field.
Ed made anything past 12 yards dangerous AND he could blitz AND he did run fits like a proper safety.
For me, if you're choosing between a top tier safety vs a top tier corner you choose safety every single time.
