James Harrison has been one of the better defensive players over the last decade or so, but his production has dropped off in recent seasons, which led to his release by the Pittsburgh Steelers when he declined to restructure his contract. Still, that's not stopping Harrison's agent, Bill Parise, from trying to drum up interest.
According to NOLA.com, Parise has suggested that Harrison would be a "great fit," for the New Orleans Saints. Then, according to the Baltimore Sun, Parise suggested that Harrison is interested in joining the Baltimore Ravens. Parise also called Baltimore a "great fit."
When talking about the Ravens, Parise specifically noted that the Ravens will need Harrison due to the "market for Kruger," referring to outside linebacker Paul Kruger. It's likely that Kruger is going to get a big contract once free agency opens, and it's unlikely that the Ravens will be able to afford him under the current salary cap.
Of course, there's nothing actually linking the Ravens to Harrison aside from Parise suggesting it would be a good fit. It does seem to make sense given the need at linebacker for the Ravens, but given that Harrison's production led to him netting just six sacks in 2012, he would definitely be a step down for Baltimore.
As far as the Saints are concerned, they could definitely have a need for Harrison. New Orleans is making a switch to the 3-4 defense and they may or may not have the personnel to do so. Junior Galette will likely be one outside linebacker after agreeing to a new contract on Saturday, but the other spot might be open.
Currently, it looks like it could go to Martez Wilson, but he's not been much of a pass rusher thus far in his career, and many have felt that he belongs in the middle. Harrison could either battle with Wilson for that starting spot, or he could be a reliable backup in the case that either player doesn't pan out in the new defensive scheme.
