Help me out with these Safeties.....

I have Weddle and he's been good, but..... no one has picked up Wilson yet (I know, shocking) and Mikell is also still available and so is Bryan Scott. I'm only going to carry one DB so I need to make it count. It's pretty much a tackle-heavy league. Rank these four for me for the rest of the year:

Weddle
Wilson
Mikell
Scott


painkiller

I'd rank them as follows:

Wilson
Weddle
Mikell
Scott
