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.

Be mindful that introducing a new leader into a tight group that already has one can upset the applecart.

Vilma has never lead this group, under this coach.

Vilma and Lofton were both leaders and worked together last year, I recall them both saying they enjoyed and fed off each other. I don't see how a coaching change upsets anything

If you don't understand the dynamic and how it has changed from last year, then I can't help.
