Leeds have also signed Yates from Hunslet for next season and I think Wire may look to the championship again to replace one of Moz or Carvell.
For this reason I am not overly concerned about players leaving for the NRL.
The players leaving for the NRL include many quality players from down under who can now get a decent contract back home, in addition too many quality british players are leaving as well.
It stands to reason that if you take top players out of Superlegue then Superleague has to replace them. Not easy to do that via overseas players and so they are replaced mainly by Superleague academy players and some late developers from Championship clubs some of which don't originate from the championship clubs but came through the academy system.
There's no change to the reality that the Superleague clubs and their academies will continue to develop the most players, there's no change to the reality that a few players will get to Superleague via the championship, but let's not kid ourselves championship clubs are suddenly churning out the stars because they are not.
I'd like to see a list of the top 50 players who have walked away from Superleague and a list of the 50players who have a Superleague contract only because of that. I think you will (with respect to the players) apart from exceptions (which people will constantly point to like "Zac") find that we have a problem in the reducing quality of our Superleague players, and certainly not a championship that is suddenly producing professional quality players.
AFAIK Yates was signed by Hunslet from St.Helens where he hadn't made the grade but retained great promise. I suspect Leeds coaching team had a hand in the lad ending up at Hunslet. Top Hunslet lads like Baldwinson and Sutcliffe circumvent the Championship. We can wishful think all we want, but when "feeder clubs" feed lads into the SL clubs like this let's not delude ourselves they are turning up the stars of tommorrow for Superleague.
