Sorry about the Irish thing, that mistake has already been acknowledged but nothing a google can't solve.
Nothing wrong with devils advocate to get the juices flowing, that's why I'm not criticising you, just putting up alternatives with a small level of grounding, and would appreciate the same. On the same note, no one has seen 2017 Jeffries play either. This is all guess work and theory
I absolutely agree that Schatz is a great option as you said, but I think that having 2 inexperienced 2nd rowers in jeffries and timani, with only a recent introduction in schatz as a known lineout entity, could lead to some setpiece and lineout woes. I like jeffries, but I see him as more of a Douglas then Simmons (aggressive country lad v set piece)
