very important i think to re-sign Reid, Neville and Hegarty. Reid may well stay on, there aren't too many back row opportunities elsewhere, Neville seems to be on the outer but may not be offered a gig at another franchise. Hegarty is the most likely to be poached, he has been really good since his arrival and i rate him a must keep to cover 10,15 from bench, but he would surely be on the Reds radar though one would think.
Probably one of Sexton and Whittaker will also re-sign. I would try to keep Kingston also, not sure we need both he and Veainu, whom i also rate highly, but the latter has obviously slipped down the pecking order.
