What I was saying is that it's both. Before thrash, and especially for early nwobhm there is a lot of prog to it. Prog was actually trying to remove the rock/blues earlier than nwobhm, and even if such and such nwobhm band said they hated prog, their structure is much more like prog than hard rock. No swing, square beats, linear and through composed songwriting, etc.

NWOBHM tried to streamline it of course and they succeeded to an extent but as I theorized before, it took hardcore to actually invent the tools to finally achieve that goal completely and result in chromatic labyrinths. Ie its not hardcore alone, nor prog alone, both had to be part of metal's dna to result in death metal in my view personally.
