I'd love a safety, but I think the front seven needs attention before the secondary. I understand the secondary is bad, but I think it improves with improved pass rush.
The thing is that we will need to attack some needs on free agency and some during the draft. This year is not realistic to think that we will fill all the holes in free agency and look for the best player available in the draft.
That is why I am concentrating on safety at free agency. To be honest, it will come cheaper then to grab a lineman or linebacker. These two positions then, can be looked at the draft then.
At the end, it all depends on what is going to happen with Bushrod. He is the key of this offseason, for good or bad.
