When healthy, Welker has always been someone to help move the chains, which means more time of possession, better for Green Bay's defense. If he does a 1 year deal at a team friendly price, it could work. Plus, he has returned punts. It certainly could put that much more pressure on the opposing defenses.

Honestly, I don't know if there is a free agent ILB who would be any more than camp competition/depth. A productive starter from the available list of LB's would be something.

The other positions that need fixing will just have to be fixed by 2nd and 3rd year guys on the team who have hopefully developed, and the draft and college free agency.
