If I ran a SL club I would want to keep my reserve team costs as low as possible. To do that I would need to play players who are cheap (the youngsters) or I see as needing to get fit (Not likely to go on DR as can be monitored better). For other players, not in contention that week for a SL game, I would want to get some money back to help cover costs - so I would send them on DR to pay part of their salary.

We have also not had clarity on the number of reserve games each season (ie is it one league, conferences, or even divisions. One, two or even three game against each team) this will also be important

Based on this I see little change in the availability of players for DR

For me it wouldn't be a bad idea if next season some sort of rule was brought in to try and prevent certain types of very experienced SL players playing on DR. For instance, although Brad Singleton was made available to Fev because he wasn't selected by Leeds, I agree with those who say that's not the type of player who should be playing on DR, there are plenty of similar examples (Adrian Morley is one who comes to mind). Maybe a rule that says you have to have played fewer than 50 SL/NRL games, or not played at that level for at least a year, to be eligible for DR.

Or just dump it altogether?

Fine by me if they do, but that ship might have sailed. The Championship has become so much stronger that I can't see it being contested exclusively by third-tier players. By that I mean - the top 200 players roughly make up the starting 17 in the 12 SL teams, the next 200 are the remaining SL squad members, and Championship clubs would be left to select from that third tier, players outside the top 400. The smarter Championship chairmen have realised that there's not much point in paying, say, a 20k salary to attract the 400th best player in the country when you can use the 250th-best or 300th best player on loan or on DR.
