Some FA CBs to look at...
Florence would be a stop gap type player. I read that he's best as a nickel back and I feel we need a #1 or #2 considering our position.
After the top three: Samuel, Asomugha and Trufant.... Florence is ranked fourth. The talent level falls dramatically though with Florence on down. Some others though by rank would be: Brian Kelly(Tampa), Eric Green (Zona), Randall Gay (NE), Reynaldo Hill (Titans) and Jason Webster (Buffalo).
We may have no choice but to go after some of these guys. At the moment I'm just not sure which of these guys may have it in them to take it to the next level. Can any be trusted to man up on a receiver?
