Nnamdi Asomugha, Braylon Edwards and Mike Sims-Walker have all found new homes.
Randy Moss and Marc Bulger have decided to retire, at least until a decent offer comes along.
That leaves the free-agent market looking pretty bare at the moment.
Lofa Tatupu, formerly of the Seattle Seahawks, is still looking for work.
But, is he the best free agent remaining?
Probably not, because wide receiver Steve Smith, formerly of the New York Giants, is still looking for a new team.
Smith is younger and more dynamic than Tatupu.
But, Tatupu is definitely the best defensive player still left in free agency, after Ben Leber signed with the St. Louis Rams on Tuesday.
He's a guy who has a nose for the football, with five seasons of more than 85 tackles.
But, teams haven't come calling yet, despite plenty of teams having needs at the linebacker position.
The Oakland Raiders and Chicago Bears probably need help. But, the Raiders have been quiet and the Bears insist they are happy with Nick Roach as their starter.
Heck, even the Philadelphia Eagles could use some help at linebacker. And, since they've signed every other notable free agent this offseason, why not Tatupu?
He knows how to make plays, both in the run game and the passing game. He has 10 career interceptions and seven forced fumbles in his seven-year career.
One concern the Bears had was Tatupu's ability to play outside linebacker. But, seeing as how he is good in pass coverage and has the ability to make stops in the run game, it shouldn't be a problem.
His biggest problem is pass-rushing, but he can work on that since he's never really had to do it in his career thus far.
Whoever ends up signing Tatupu will be getting a very solid linebacker, and, the best remaining defensive player on the free agent market.
