I personally believe we should keep Yarran, but my thoughts would be MM would trade him in a heartbeat for a pick inside the top 10.
If we improve in areas we need to I think Yarran will be a beneficiary. That along with getting himself a lot fitter.
For example if we can get more run into the team (particularly through the middle of the ground) and we've started that process with Thomas Yarran will benefit from the more space it will create.
He's not and never will be a contested ball monster, his weapon is in finding space and using run and carry. With more two way run in the team he will find space, particularly on the counter a lot easier to come by.
