He never moved to defence until 2014, in which he was in AA contention by the end of the year, was the clear AA by the next. Then, at the absolute peak of his career, the suspensions happened.
Prior to that… The only thing he brought to the table as a forward was his one-on-one and body work, it certainly was never his marking. Plus, he’d regularly get moved back, and not because we needed somebody to get 30 loose touches, but because a big forward had got out of hand and Hurley had to stop them.
Prior to 2017, his entire career was built on being a consistent one-on-one player, and a damn strong one.
As for which injury hurt him the most… Who knows? But his wrists were cooked about 5 years before he suddenly couldn’t defend anymore.
