I think the prior posters on this thread are correct. We will likely hear about Harrington, one way or another and/or a differant QB to help with passing drills. The Lavar Arrington situation may work itself out though I would think the ball is in Arrington's court as to what he wants to do. I'm more and more expecting a one year contract perhaps with an option so he can prove his legs are ready to go.
For the fins, you may see another second tier signing, such as Pearson, but those will probably be "fill-ins" after the draft shows us what we will still need.
