You'll have to forgive me for not accepting the definition a website none of us have heard of. Many observers and pundits have expressed surprise at the fact that Casemiro offered so much in possession last season compared to their understanding that he was a pure destroyer, despite the fact that his statistical profile at Madrid didn't support this assertion anyway.
The reason this conversation started was my statement that pure destroyers have no place in a modern progressive side - you have to offer something in possession too, which I do not believe Rice has shown in his career thus far. Casemiro was brought up as an example of someone who potentially doesn't fit with my assertion on the basis that he isn't the best at deep build-up, a statement that I would agree with. My argument is that Casemiro does offer something in possession, as can be seen by the fact that he ranks highly for progressive passing, passes into the final third, assists and expected assists. Whilst this isn't what one would ordinarily expect from a defensive midfielder, it means he doesn't falls into the archetype of a pure destroyer and therefore my original assertion stands.
