I say the time is now to give Omar Brown a shot at Free Safety!
We really do not have the time to draft and develop a rookie FS. It may take that rookie a while to get accustomed to the NFL style Defense let alone our D.
Omar Brown has been with the team for a couple years now so he's not a rookie. He has experience, which is what the team prefers. He has had more than enough time to develop.
Why do you think his nickname is "Baby Ed Reed" . I'm sure Ed Reed has been taking him under his wing for some reason. Big Ed wouldn't mentor him if he didn't have potential or even reminded him of himself in his younger days.
