assuming many have already watched this but thought id post anyway
really interesting schematic talk from Harbs about versatility in the defence with regards to coverages etc. and how they re-organised the defence in 2018 (question starts from about 7:28)
also very much get the sense that Simpson is not a PQ replacement at all - that they view him as a versatile matchup weapon (at least early) who may at times have us have 3 LBs on the field at once
