He definitely is the beast at the moment- outstanding form. He was good last year too when the team was very average.
I'm not sure I'd like him at centre- he is good attacking with one other quick and strong bloke outside him.
Pommeroy made some errors, but so did all the backs, and he does look threatening when he can hang on to the ball. I'd be happy if we could get a good upgrade to Pommeroy, but I don't know if we should try to manufacture one. We need a general improvement all round from the backs, not just a forward swapped into their ranks.
Bakuya should definitely start somewhere though.
