I agree...Jonte Green, Rod Sweating and Mario Butler are a bunch of annual training camp scrubs. Green was cut by the Lions, who have long been desperate for cornerbacks. Brooks and Cockrell are the only CB's out of that group who have a shot at making the team. (Besides Gilmore, McKelvin, Graham, Robey.) Nobody is trading for Cockrell, Ladler or Meeks, either...they've done absolutely nothing.
And if Searcy walks, he will most likely be replaced by a platoon of Duke and Rambo, like how they replaced Byrd with Duke and Searcy...either way, I really don't think this is a concern, at all.
