Now you are getting confusing
. A Nose Tackle plays a 0-1 tech from what I know and and under tackle plays a 3 tech on either the strong side or the weak side depending on if they are playing an over or under alignment. So are you looking for a nose tackle to line up right over the center and either take him straight up or shadow the strong side gap or are you looking for an undertackle that lines up outside the guard? Or are you talking about one guy who can play all of those spots from straight up over the center to the Guards outside shoulder?
