Eagles fired their OC Brian Johnson

That's a bit of an exaggeration. It's pretty clear to all that the offense mostly held the Saints back this season, and they were one game away from the playoffs and have some very good pieces to work with on offense. I don't see how anyone hoping to be an OC doesn't look at the Saints and get excited because the pieces to be good are already there. If DA gets a good OC, they are winning the division next year.
Because several times the players and the coaches poked at each other several times, and the GM doubled down on the players. That’s an awful situation to work in.
Also, for the time being we have a terrible OL, not the best to make you shine as an OC
