I'm with big Jim on this one. I was expecting a grade C charge. At the end of the day it doesn't really matter what Tasi does, as a 3rd man in you have to be very careful on how you enter the tackle and Sam was too low putting undue pressure on Tasi's knee.
If you watch us this year the 3rd man in now enters the tackle round the waist and skills down thus avoiding the ''cannonball'', Sam just got it wrong.
Same principle with Tasi's charge, TT was going down but Tasi made direct contact, shoulder to head.
