Giving extensions will clear up cap space for the current year, almost as good as released due to the NFLs accounting method.
Amos should get an extension.
I'm not sure what to do with Turner and Lowry, they're good enough you don't want to let them go, but not good enough you large large money at them. Solid starters, though ideally you'd want someone better, but they're like glue guys, keep everyone else together but not a play maker themselves.
Cobb, if we're keeping Rodgers then give Cobb an extension, but his dollar amount has to drop, with all due respect, Cobb simply hasn't lived up to his contract amount, he's good enough to keep around especially with his Chemistry with Rodgers, but he's a #3 WR at best now... then again, that's sort of the Packers problem, they have a #1 in Adams and then no #2 recievers and a bunch of #3 or #4 WRs after that.
They need to upgrade the receiver role, and not it doesn't nessarily have to be WR, but a great threat at TE could work as well like it has for the Chiefs and 49ers. But it can't all be Adams.
MVS speed helps open some stuff up... but he's a FA too.
