The biggest problem that we have with Bachar Houli is that there's only one of him.
Let's imagine that instead of say, Jake Batchelor (when he plays medium) we had someone like Pittard in the role. And instead of Newman or Morris, we played Malceski.
Would other teams be able to cut our run by dragging Houli back to the square?
It's pretty simple. Every year you plan how you'll add run to your backline. Add it this year, next, the one after. Plan it.
In the 2014 drafts we took four or more players who could add run. How many did we draft in previous years? None? That's a low number. Whoever decided on adding that number has to be subtracted.
If Castagna were ready to go Houli would find more space straight away.
