If Mosey is coming back, and it looks almost guaranteed that he is, then I would much prefer him as a forward. If he does he would slot in to that 3rd winger role, and playing with Waller that line would have serious wheels. And a bigger guy in Busch in the middle to make space and get them the puck, it could work well. That would leave 2 d men, I'm hoping Crawford is back. And if Jardine is not I would go for an old fashioned stay at home d man.
Obviously that does put Barrow in the top 6. He could be up to it, his start last year would suggest he could be, but we'll have to see him play first.
One thing that's a slight worry for me is that Ully and Barrow are coming back from significant injuries. Mosey is guaranteed to miss half a season too. Maybe getting Chad as a spare isn't a bad shout actually.
