Plenty of negotiations being done, especially outside backs and fullback. The DT reporting a maybe swap deal between Sloan and Sami for example (apologies cannot post link)
As for half back, the emergence of Reed has stymied any current talks. If Reed develops sufficiently over this year, he would be our half moving forward. A decent half from outside would demand a minimum of 3yrs to even open talks. That in turn would block Reed's path. Atkinson is and will be an asset in the halves moving forward. We also have O'Neil who was at one point touted as a very good half.
Things happening just not quickly enough to satisfy atm.
