Unlike the other three members of this list, Reed Doughty has a sizable sample group to pull from.
We know what he is (or perhaps isn't) capable of heading into 2012, and he surely falls into the category of experienced players who are fighting and clawing to keep younger, potentially more talented players from taking their roster spots.
Doughty is seven years in now, and for the Northern Colorado alum, it's crunch time.
Doughty has been serviceable during his time with the Redskins, but apart from that, there is not too much more you can say. He's had at least 88 tackles over the last three seasons, which certainly is a positive.
Yet Doughty lacks big in terms of coverage ability, and too often, he gets beat by opposing players who are either much stronger or much faster than the 5'10" Colorado native.
Injuries have been huge in the secondary, though, and Doughty has had to pick up a lion's share of the slack over recent years, meaning his experience is surely something to consider.
Brandon Meriweather, despite getting media coverage for the wrong reasons recently, is under contract. Tanard Jackson is by no means an All-Pro, but he did fare well during his time under Raheem Morris' watch in Tampa, and there's no reason to think he won't be able to replicate that success in DC.
Cedric Griffin will also likely be splitting time at safety this year, as he is arguably the most versatile player on the Redskins secondary.
You might be surprised on the outset to see Doughty on the sidelines come Week 1.
But when you think about depth concerns and the lingering reality that the Redskins are without a star safety for the first time since 2003, it doesn't sound so bad having Doughty hanging around after all.
Not to mention he can continue to put in work on special teams. Note to the Redskins' new class: It might not be stylish, but it keeps you employed.
