Himmelberg is our best Thilthorp replacement and best for our structure of having a tall that we can bomb it in high to if we have a flooded forward line. He is our best bet for a second ruck too.Burgess would be more of a like for like for Tex or Fogarty. We have played the three together and it does not work. Gollant has been tried in the third tall role and found wanting. For team balance I am happy with Himmelberg's inclusion as he can play back up ruck. It remains to be seen how he goes up forward, but can't be worse than anything else we have tired in Thilthorpe's absence.
