Looking at the stats* in Super Rugby so far:
In terms of scrum success the top three teams are Chiefs, Blues and Crusaders. Of the top 10 team only the wee stormers and Lions make the grade.
In terms of line out success only the Bulls (is it due to the influence of the long haired master Victor Matfield?), Lions and Sharks make it into the top 10. The mighty Chiefs are 5th.
For tackle success (not just forwards) only the Sharks and stormers make it into the top 10 (6th and 7th respectively).
Now Moz may say that de Allende and PSDT account for 90% of the missed tackles but he would be hard pressed to prove that… not that that's ever stopped him before.
