It is not out of the ordinary to see a kicker or punter come through with a tackle after a returner has gotten past the rest of the kicking team. But you may never see a bigger hit delivered by a kicker than the one by Pat McAfee of the Colts on Trindon Holliday of the Broncos during a kick return.
