Seattle was reportedly trying in bring Winfield back after releasing him at the start of the regular season, which makes sense given that Brandon Browner was suspended for a second time just a few weeks ago.
The Seahawks elected to sign Perrish Cox for the time being, but Byron Maxwell and Jeremy Lane have done a pretty good job of mitigating the impact of losing Browner. Of course, it also helps to have Richard Sherman and Earl Thomas in your secondary.
Winfield, 36, was a three-time Pro Bowl selection who played his best years for the Minnesota Vikings. Despite his age, Winfield put together a heck of 2012 season and has had a very solid career in the NFL.
