I'd say the one year deal would be due to his injury problems of late.
I think if it's true it's a great signing. We have gone through long periods of the year with zero depth, now we go into 2017 with Sutton, turner and rochow who are experienced and chricton and Gosiewski have a year under the belt.
The only thing that mighy worry people is a lack of run metres. At newcastle, especially over the last few seasons, he has been the senior forward and has been playing more towards the middle meaningbhe has had high stats due to a high work load. At souths he is more likely to be stuck on the edge and do his role in Maguire's systems, where 2nd rowers rarely run over 100m a game, and just focus on running at holed and set plays. He was good in this role during Bennetts time at the knights
