It's a very interesting question. Clearly Lowden won't replace sauce. Suggest Lowden will battle primarily with JJ for a look in at 2nd ruck/KPF.Hows does the Ruck situation work next year? Does it stay Jacobs with Jenkins backing him up? Does Lowden get in? How does that impact the big forwards?
Of course if sauce is injured then Lowden comes in to back up and we just get by sharing duties with JJ
