Fackrell is also a FA after this year. He is a guy I suspect Packers probably let walk as a FA With the Smith Bros and Gary I can't see the the team wanting to pay him a increased salary to be a backup LB.Blake will get more than the Packers can pay.
Hopefully Ty Summers will take a second year step, just like Blake did. Maybe Burks will finally get up to speed.
At any rate, we can find a run stuffer. What we need is a guy who can cover. Maybe move Fackrell inside.
