The role of a lock has changed a lot over the last couple of seasons. The bill pedan, brad fitler matt hilder type players are now a thing of the past. Generally locks are either another front rower ie Gallen or a second rower who plays in the middle of the field ie Jeremy smith. I don't know if Gidley is suited to that position in the current era. All I know is, there is one position that he can actually handle and that is fullback. Apart from some games at 5/8 many years ago, he has been out of his depth in every position he's played.
