According to McLane:
"I can confirm reports that the #Eagles are now serious players to sign S Yeremiah Bell. It's between them and the #Jets, per an NFL source."
A 34-year-old safety, Bell makes sense for both the Eagles and Jets. Both teams are in need of a physical presence at safety, and although Bell is certainly aging, he compiled over 100 total tackles for the Miami Dolphins each of the past four seasons. Bell does not excel in coverage, but he is a an extremely physical safety around the line of scrimmage.
Bell may have some added incentive to join the Eagles after ex-Miami Dolphin interim head coach Todd Bowles joined their coaching staff as the defensive backs coach this offseason.
According to Mike Florio of Profootballtalk.com, the Eagles may in fact be the front-runner.
As it turned out, Rosenhaus spent much of his time on Thursday finalizing a contract for Eagles running back LeSean McCoy. Since Rosenhaus finished the job by going to Philly and because he specifically said that he’s “on my way” to visit the mystery team, it doesn't take an advanced degree in astrophysics to conclude that the Eagles are the mystery team.
