Pass and Evans have been replaced by Mills at "fullback" , to the degree either was ever a fullback. Perhaps in reality Mills replaces the 6th WR, a roster spot on the 2005 team.
In any case, Pass needs to win a special teams spot. He has done so on several occasions, to my mind, in every season he's been here. He seems to find a way to win one of the last three spots which are always up for grabs.
