I'd like to see Gidley used as a starting hooker, and then move to a sort of "roving lock" position when, hopefully, Buderus comes on. Similar to the way the Roosters accommodated Pearce, Anasta and Carney all in the starting side last year. Gidley may not be the size of your typical backrower, but he has shown every week that he is capable of tackling and running into the big blokes closer to the middle of the field.
But in all likeliness, I see him playing in the #7 each week with Roberts and Stig running around for the Centurions.
