Yep you were arrogant. It wasn't confidence, it was arrogance. No semantics can change that.
Arrogance? Mate arrogance was thinking that 'Martin is going to strong arm the entire Adelaide team' or that 'Rance will destroy Walker' or 'Nankervis will thrash Jacobs'.
You came up against a good team and got put in your place. As a team of mediocre talent who get ahead of themselves every single year and are the epitome of mediocrity in the AFL.
