I dunno about their rating system. I think it's flawed.
I question a lot of the way CD measure their stats and efficiency.
I've said it before and I'll say it again, the definition for disposal efficiency is the biggest load of bullocks and absolutely gives an erroneous view. If a player kicks it long(over 30metres) to a 1 on 3 contest it should not be classified as an efficient kick. If someone kicks it into space for a teammate to run onto that should not be classified as an inefficient kick, or if some dufus teammate drops an easy mark and the ball gets turned over, itshould not be classified as an inefficient kick. If a player like Bellis kicks it short 20 metres sideways or backwards, when someone was on 45 down the ground is it efficient? Its flawed. Dusty goes for line splitting passes that sometimes dont come off so we have a situation where plebs with nfi question his skill bc his disposal efficiency is at 65% vs some hack defender who passes it sideway and has a rating of 80%+
Like in soccer, they talk about pass completion rates like its an important stat, so you have limited footballers who just go sideways and backwards with a 90%+ completion rate as opposed to the suarez/Messi types who continue to go for the outrageous defence splitting passes but dont always pull it off, then you have couch experts arguing that player x is the best on the planet bc he hits 5-10 metres passes all day long.
