If the offense keeps rolling the way it has (in the 2/3 games we won), I can't get too disappointed about Sammy's numbers. If the offense is working out and Harvin/Woods/Clay are the ones getting big yards I see no reason to change approach.
That said, I think the nature of our offense (which forces a lot of missmatches with all of our skill players) is that some weeks certain players will have quiet outings.
Sammy'll rip off a couple big ones soon.
