Free safety is a player who can double-cover another player. He has no particular receiver to cover.
Ronnie Lott and Ed Reed are the top two contenders for the best free safety in NFL history.
The former had a great tackling ability and communication skills, while the latter could frustrate even the likes of Tom Brady.
Lott retired in 1995, whereas Reed retired in 2015.
Presently, Lott has two car dealerships and is an adviser to the athletes.
