I would say that Hanigan got through a ton more work without as much grunt. He was much more accurate.
LSL (Lukhan Salakaia-Loto) seemingly has it locked down. The only other person given a run has been Jones for 10 minutes?
For all the talk of trying other options there have been few alternatives trialed in most positions.
I've done some stats stuff for the SUper Rugby season. Now we all now stats don't tell the full story, but they act as a guide I guess.
Unfortunately I don't have minutes played nor ruck involvements. Just the basics. But some observations of the players that started at 6 for their teams (min 3 starts).
Match involvement (simply, the number of runs they made plus the number of tackles attempted) per game:
1 Luke Jones & Angus Scott Young with 19.25 involvements per game
3 Ned Hanigan 17.5
4 Lachie Swinton 17.17
5 Luckan Salakai-Loto 16.75
6 J Dempsey 16
7 A Cottrell 15.33
8 R Valetini 15
9 T Cusack 14.5
10 P Samu 13.75
Tackle effectiveness (%ge of missed tackles of total tackle efforts)
1 Valetini 56 efforts @ 94.64%
2 Dempsey 25 @ 92%
3 Hanigan 67 @ 89.55%
4 Jones 97 @ 88.66%
5 Scott-Young 102 @ 88.24%
6 Swinton 62 @ 87.10%
7 Samu 32 @ 84.38%
8 Cusack 39 @ 82.05%
9 Cottrell 58 @ 81.03%
10 Salakai-Loto 75 @ 78.67%
Hanigan's efforts are there, but I guess impact is what let's him down.
Samu's numbers are very low. Perhaps just an impact player.
LSL (Lukhan Salakaia-Loto) has significant defensive issues while at 6.
