I wouldn't mind Polomolu. Still plays at a high level and is good in coverage. Something we need from our safeties. Suggs, and Ware are fairly interesting too. That is assuming these guys actually get cut.
No to Burleson, old and injury issues. Would love Delmas if he isn't too expensive. He's likely to be in demand.
I'll be surprised if Polamalu leaves the Steelers. If he does, you can rest assured that he's pretty much done as a player. He was getting beat with some regularity this past season. He's a shell of what he was.
