Walker, Johnston, keary, Reynolds, gray, gresmvual, burgess x2 have all signed upgraded deals. A lot of those guys would be on marquee money now
Walker, AJ and Gray (isn't in our best 17) aren't on that much. But yes they have been upgraded and Grevsmuhl has had a bit of an upgrade too (clause activated in his contract for 2016).
Keary and Reynolds are on 500k for 2016. McQueen gets 280-300k for 2016.
GI on about 800-850k I reckon.
Goodwin and Auva'a aren't on that much. Sutton is pretty much free due to how long he's been with Souths.
The following guys aren't on that much either, Oldfield, C. Walker, Cook, Mcinnes, Tyrrell, Clark, Turner, Carter, Brown, Musgrove.
Souths could look to get rid of Grant to make room for Sam too as DKOR said.
Souths depth isn't the best next season and we have the least amount of contracted players for 2016 with 25 signed currently.
Stewart will free up $600k, Issac will free up about 500k. Losing Te'o freed up money too.
Vic if Sam wants to come back we will have enough to fit him in. They'll have it planned out.
I'm not getting my hopes up though at this stage!!! It's all just speculation.
