I'm not a big fan of Briggs. I wouldn't mind sending him packing and help get up in better cap shape. There are a lot of FA LB's out there tha6t can do more than Briggs can at the same cost or maybe less.
He was playing good, not great, but ultimately ending up not being the leader that he was asked to be. Returning that out of shape and refusing to stand up and being the voice of the defense is uncalled for considering how much he has always cried about wanting to be the man. I wouldn't be upset if we told him to take a hike.
