Gotta be poor fundamentals - Wasps were playing bin juice ahead of him at 2 before
I'm not sure if playing 8 is that easier of a path - Binny coming back to form, Dombrandt and Simmonds in the squad, Curry playing there for some reason
I do expect him to get into the backrow sooner rather than later, but we've little depth at 2 for England, and at the time he would've been making his decision we were down to the bare bones and if he were any good he'd have waltzed into the side at 2
Wasps also have Willis at 8, and no one special at hooker (Frost looks really promising, but Oghre isn't great), so they'd have kept him there if he was good
