Right here and now, I agree there is no clear path for him. But IMHO he needs to spend at least 1 season in ISC and who knows what happens in a years time.
If he is ripping it up in the ISC and demands inclusion, then the club has to make a tough call and move whichever one of barba/hunt/milford he is better than either to the bench on move them on. I don't really see what the problem is. He is under contract for another 2 years and in that time they should have a fair idea whether he will cut it or not.
In relation to RNA's comments below that he may be another alfie/DCE - He may well be, but corey norman looked the same in the NYC, until the at least play some ISC you just can't tell IMO.
