Interesting post at the end of the Linked Article - Harvin's return to the Seahawks is more important or more of an impact than Vilma's return to the Saints. Not quite so sure on that one.

It's difficult to compare two players so radically different. I really think the return of a leader on the D and another warm body in there makes a massive difference to our whole team. Whilst Harvin is a superb player and a great addition to their team, they have hardly been struggling offensively so another option he may be, but not a massive changer to how they have been performing thus far.

I'd say it's a big boost for both teams.
