OK but 3 of the players you mention weren't playing, so it doesn't really matter what they are being paid.
I either case I wouldn't have thought they cost much. Lineham and Myler are probably in their last season and won't be getting much, I would have thought, but I am speculating.
As for the size of the squad, many are simply squad players and aren't really Championship standard but would be classed as "in development".
I thought York were very poor today. Without Thompson and Jubb an already light pack left the middle wide open. Hingano looked a threat but played behind a dominated pack. Without Myler and Nikau Williams York had very little creativity.
Still, even without these they were poor. Never looked like competing, even against 12..
