Even though the Bengals lost out on their two defensive linemen, Frostee Rucker and Jonathan Fanene, they still have a shot at arguably their most important free agent--safety Reggie Nelson. Another key backup, Anthony Collins was thought to be seeking a starting job somewhere. It has been reported via The Cincinnati Enquirer's Joe Reedy that the team has reached out to Nelson twice this week and no progress has been made on an extension. It also appears that the Bengals aren't the only team that feels as if Nelson and Collins may be overvaluing themselves.
According to Evan Silva of Profootballtalk.com and Rotoworld.com, the market on both have been quiet and there has been "nary a peep".
It's entirely possible that both players have overplayed their hands and have been passed over for other capable players at their respective positions that are still on the market. For instance, a player that is considered a less quality safety, Haruki Nakamura, has been invited for a visit with the Panthers. We haven't heard anything about a visit with Nelson. The market has also been quiet with defensive tackle Pat Sims along with Collins and Nelson, as we haven't heard any rumors about him either.
Most people assumed that keeping these three was a remote possibility, but given the low interest out there it seems as if the Bengals' chances of retaining them have increased. Perhaps the team was actually pretty astute in their decision to no franchise tag any of these three.
