Who are the Rams eyeing, right now, as their top priority FA (not on the team)

I wonder who Snead may have on the radar as of today who is not currently on our roster? I'm sure he'll be determined to keep Dotson and Jackson. Dotson will be costly, and Jackson will be relatively easy to hang on to. After that, probably Witherspoon and Robinson, but I don't think they'll spend big on either.

So, who might the Rams be eyeballing?

My guess is Brian Burns. Clearly the Rams have coveted this guy for quite awhile.
If he's just too much, Greenard of Houston might be #2.
