It's possible all of them are, and none of them are. Wow, what a definitive answer for you, huh? Let's unpack each of these on their own:
Clay Matthews: He's not an elite pass rusher anymore, and won't be paid like it. Nor should his role for any defense be rushing the passer 75 percent of snaps. But he's a heady veteran who knows the game, and he's got enough athleticism to be a rangy player off the ball. His versatility is an asset. On the right deal, say about $5 million, I think he has value to the Packers as a linebacker who can split time off the ball and rushing from various positions as a No. 3 OLB. If not that, then no.
Nick Perry: He's the one guy I can't seem coming back. Too injury prone. Hasn't been that productive when healthy. His original contract called for a potential out after three years and it's only been two, but probably time to cut the losses.
Randall Cobb: His quarterback sure seemed to stump for him yesterday. And watching the Packers offense this season, Aaron Rodgers has a point. Cobb gives them something they don't have otherwise, a slot receiver who can really work the underneath stuff well, especially those 8- to 10-yard slants. But the Packers are loaded with developmental talent at the position. Rookies EQ and MVS could really take off, and Geronimo Allison is now a veteran who has shown good chemistry with the QB. So the Packers are positioned to move on.
Bryan Bulaga: Yes, the Packers could upgrade here for sure. It's hard to trust Bulaga can stay healthy, especially with his 30-year-old season coming next year. But I thought the Packers could make a change at RT last year with Bulaga coming off the torn ACL, and they stayed with him. The reason: they had so many other things to address. Just like this offseason. So I wonder if they put RT on the back burner again, focus on other areas and have Bulaga play out the final year of his contract in 2019.
As for Jimmy Graham and Lance Kendricks...
