Ross wasn’t discarded, though, was he? We would happily have kept him, but Ireland basically offered him a track to international caps, on which they delivered.
I think you'll find it was the same for Treadwell, capped against Japan last year, so I would'nt class him as discarded either.
I think the current 12 (whoever they are) can be classed as 'discarded' though. Can't help think looking at some of those coming in that 'we're' just book balancing, pay wise though. ie bringing in cheaper options to sit on the sidelines
