What Does Funk Really Offer on Special Teams?

Not sure, he's not a kick returner, now maybe as a gunner perhaps, but I've not seen it. I will be honest I've never been a fan of Funk, didn't like his injury history at Maryland and he just does not look natural at RB, more straight line speed, can't make the first man miss plus is not elusive. I would add someone else that shakes free. Again, I don't understand what Funk truly brings to the table.
