All things equal, you take the pass rusher. Unfortunately, I don't believe that there is a way to guarantee that we get Suggs. So, the question for me is, do we not try and resign Dansby before he hits the open market, and instead bank of the fact that we can outbid the league for Suggs. Keep in mind that this includes the team that he just said should keep it's core of linebackers in the Ravens.
If I am an organization, I can't take this risk. If we want Suggs, we are going to have to pay both him and Dansby because we can't risk losing out on both. The only option that prevents this is in tagging Dansby again, which he won't like.
