If Sailor is coming then 3 of last season's team will have given way to accommodate him.
Joe Mellor has been released, I assume because Sailor provides cover at half back - although Joe of course was being used last season as backup hooker. Sailor is coming as a direct threat to O'Brien's position at full back and for the moment I don't see how the two will play in the same team unless something happens to either Moylan or Lam who will otherwise be the starting half backs.
Lastly, it must also mean that sadly Big Ben will have to be released.
For all this to happen Sailor really must be considered to be a significant upgrade by the powers that be.
As said before on this thread, there is suddenly no room for sentiment in these decisions. This all feels very un-Leigh like. Just goes to show how far we have come so quickly.
