You’re assuming taking McCullough off is a given.
I actually disagreed with that change, thought it was a bad move. The only thing we needed to worry about was scoring points. After all, what’s the difference between losing 22-12 and 34-12.
So, take 13 off. Leave 1, 6, 7 and 9 on the field at the same time as Milf and have him pop up like a second fullback, just follow the ball and run. Defend at fullback if need be, with Morgan at lock.
Re: Hess. On current form, Su’a would have been a better option. At least he’s running nice lines and hitting hard in defence week to week.
