I feel really sorry for Sam Cane who just seems to be massively under fire right now. He doesn't really deserve all the negative attention he gets. He wasn't my first choice for AB's captain (Whitelock is, though I was a little underwhelmed by him on the end-of-year tour) but I felt he was good on Saturday night. I think he will be better this week and get better throughout the season. He has had some injuries, but time and time again he has shown his class in black, leading from the front, and people need to leave him alone and see where we are in a few weeks.
I think people tend to undervalue his contribution in breaking teams down, so that the replacements can work their magic. It's not easy, and it's not generally noticeable but you need some grinders in a team.
