I bet you were a fan when Cordarelle Patterson ran back kickoffs last year. I think it depends on how big of a threat they are to take it to the house. That needs to be weighed against the injury risk, but IMO it would have been a shame if Patterson didn't return kickoffs last year.
Foreman is fastest person on team if you go by high school track times. And his high school fball videos were pretty impressive. Should give us more of a homerun threat on kickoffs.
