I love Yeo, but leading a pack in terms of toughness is a different kind of leadership. That's not Yeo. Stamping your physical authority on the opposition is not Yeo's thing. We need Leota, Kenny and Martin to do that and establish "You shall not pass", instilling fear in the opposition.
I have said this before, no opposition forward is checking under the bed for Yeo when they go to sleep at night. He tackles well, but nobody is booking a chiropractor after he hits you.
On the other hand, I bet plenty of them have booked Monday sessions with the Chiro after playing the Panthers. The Doctor says "how did it happen?" The player says "I was taking a hit up and then I saw these two steely eyes, sort of like a demon's, and a mop of curly hair, it was very frightening, then I just felt pain". The Doctor says "there's a lot of that going around at the moment. Its called Liam Martinitis. I can help you, but it could be worse". The player says "Worse, my ribs are killing me, how could it be worse?". The Doctor say"Well, I have had quite a few cases of Kennyitis and it is far more painful. They don't even know how it happens, they just see a flash of something below them and it stops them in their tracks. Now, let me help you get your ribs realigned"....
