Of course not. But having a stable forward pack that, as we saw last year, is capable of dominating its opposition; combined with a set of outside backs that can make something out of nothing and capitalise on half chances; plus a strong defensive structure that can suffocate opposition, the pressure on said 5/8 is going to be a lot less than it would otherwise.
I think the Broncos' priority early in the season will be, like last year, to really be strong defensively and keep opposition teams to < 16 points. That way the onus isn't on the halves to create a shitload of points, but convert pressure and field position into 3-4 tries a game. Very achievable. The last thing we want is a Henjak-esque style of play where we leak 22-26 points a game and puts the pressure on to create a minimum 5 tries a game. For a fairly generic halfback and rookie five-eighth, that's going to be very very difficult to achieve.
