Locky, Bennett and Hodges are the three that come to mind immediately, I'd have to do a bit more digging to find the others but im fairly positive there have been others. I know lock was the initial plan for him here from some of the players i know i have talked to.
All depends on the type of lock. He isnt a modern day, basically another prop sort of lock thats for sure. I've been over it before, but no other position than lock ever seemed to make real sense to me when we signed him. OF course, after his injury, i'm not convinced its the case anymore.
I think he would make a great fullback as well if he gets himself in shape. He was excellent at Cronulla there.
