It's a difficult one. I think Calvert will call it quits after this year so their is a spot their in the future.
Holiday is still young and needs to fill out he has the frame but needs some more bulk. He will def be a good player but he should be working in the gym. If he plays 10 -15 games he will have had a good season.
Burns has shown a lot of promise and is a natural try scorer. He could feel a bit aggrieved at his lack of chances but given his record but hopefully he will stick it out.
Agree though we need our local backs to be given a chance.
