Yeah Johnson was their QB coach from 2021-2022 and developed Hurts into a prominent QB in their top 3 offense in ‘22.
Still from 3rd to 7th isn’t a big dropoff worth firing. Hurts’ injuries that he played through and lack of WR depth was more to blame than Johnson. Sirianni had to convince the FO to keep his job by using quality coaches as scapegoats.
