At 22 he is still a long way off his prime (as a keeper) and has shown both positive and negative attributes which you would expect from a keeper of his age. At this stage in his career, being the number two and pushing for a first team place would be beneficial for him, he's had a taste of first team football and now fully understands the level he needs to be at. Honestly I would go back in for Joe Murphy, doing fuck all at Huddersfield and surely he would rather be playing games at this stage of his career. Wouldn't surprise me however if he hooked up with Robins again at his old club Scunthorpe.
We also shouldn't forget about Reice Charles-Cook, who should be given a go at some stage.
