CA, my reason exactly why we need to retain Suban. He's a tackling machine and his retention to teach some of the younger blokes how's it done should be a priority.
However, correct me if I'm wrong, but I'm not sure our tackle count has ever been that high under Roly - even though that Prelim vs Sydeney is often cited by commentators as the highest pressure game of AFL even played.
It's more the pressure on the ball carrier (or perceived pressure) that lead to so many turnovers - much like what Richmond did to Adelaide yesterday for most of the match.
