The 2nd KPD is a very interesting one. Other than Weiters, who is the stopper? Marchbank/McGovern/Kemp all can peel off well, but we need one of them to be able to play a more disciplined role when required.
I don't think this is McG, and he's got the best disposal of the 3. I think Marchbank has the best size to do so.
Marchbank showed at the pointy end of the season that he can play the stopper role as the 2nd KPD.
Regarding Weiters. If needed, S Durdin and Lewis Young would be our next in line for that role....in that order.
