On Mateo-IF we kept him we had to probably get rid of Ben smith or Hindy.I mean the three of them in the backrow was anot a good balance -None of them punch up the guts and hit the line hard.Im not an epxert but persoanly i think you need in the backrow a guy who tackles all game(hindy) a guy half way in between ( smith) and a guy who hits the lines and runs hard- ( prithcard style player) Other wise your leaving all the hard hit ups to the 2 props all the time.Not the balance you realy want
Just about every team looks for one back-rower to play in the middle (Hindy style) and two to play out wide (right and left).
For the tight back-row spot we have Hindy who's perfect for the position - big with a high workrate. There's a bunch og blokes who can fill in when needed.
For the wide spots we have Ben Smith (who's played on the right for several years now) and Horo (who switched with Mateo last year on the left side). There's also Maitua who will probably take over from Horo when he's back to his best) and Carl Webb can fill in out wide as well. Shackleton is also able to play in the wide role but he's more suited to Hindy's central spot.
As for front-rowers, their job is to hit up, hit up, hit up. They only play 40 minutes a game so they should be taking as many hit ups as they can. The central back-rower is there more for defence and support play than for go-forward, especially because he spends more time on the field* than the front-rowers and needs to pace himself.
*Unless your wide back-rowers can play 80 minutes in which case you could have two 40-minute central back-rowers alternating between the field and the bench. In this case you want them to rip and tear as much as the props.
Last year Mateo wasn't able to play 80 minutes in the wide spot (Ben Smith plays 80 minutes every game bar injury) so Horo had to fill in for him, as well as providing Hindy with a break here and there.
Maybe Horo can play 80 minutes wide? It would be good if Shackleton and Hindy could play 40 minutes each in the middle. Once Maitua comes back he'll definitely be playing 80 minutes a game out wide (when he does play) so then it'll probably be Horo and Shackleton fighting for the bench spot.
