You'll find it's because that 1.7 clanger a game usually results in a score from a turnover, which in turn then stands out more than a normal clanger that doesn't result in anything but just a turn over further up the ground.. Ablett will have more clangers because he has more clearances, he will get boot to ball to kick it out of congestion only to land in the hands of an opponent. It's like a heart surgeon making that one big mistake that sticks out at work as someone died, versus someone who makes more errors but those errors are less damaging.
