They're going to cut the opponents' hair so they lose their strength ...?
Was going to say, I am not aware of any sheep, rams or any such animal that is routinely shorn on our schedule.
Taking this too far, but couldn't resist some fluid mechanics:
Shear work = (power * time)/mass
So maybe he meant that if by dumb luck we're stronger for longer, we'll beat a team that's bigger than us? Sounds logical to me.
no, no that is not what he meant...
