I think you misunderstand me. I'm differentiating between a development squad contract and a "senior" pro terms contract - although you're right that strictly speaking a DS contract is pro terms. I was meaning most of the development squad will be on £350-£500p/w, as evidenced by what was stated...
When the voyeurism trial was happening last year, it was mentioned that the accused DS players were on basic DS contracts between £350 and £500p/w. I'd imagine by the time a DS guy signs his first pro terms they probably all break 4 figures p/w.
I know of a guy who was in a Prem youth set up...
