Look at their resumes. There’s probably multiple reasons EB doesn’t have a head job. I’ve read on this very site that RB coaches are not your best coaches. That is what EB has coached. And then he stepped into an OC role for a team led by Reid that won 33 games the prior 3 years. Probably has nothing to do with EB, but Adrian Peterson got 2100 two years after BE left. He was the “assistant head coach offense” for 1 year. The Vikings went 6-10 and then he was gone. Pederson and Nagy both coached in more, different roles. Both were QB coaches - probably a more significant role than RB coach. I didn’t really know the full backgrounds of these dudes but looked up the last two years hires for head coaches. EBs resume from how it looks on paper is the weakest. Hell, I don’t remember any of the others even having RB coach on their resume. That simply is not the path to head coach. You’ve got some with scouting, some with QC work, some coaching multiple positions If he’s a sorry interview, the resume and experience aren’t enough to get the job. He hasn’t called plays, he hasn’t developed anyone as best as I can tell, he hasn’t installed his offense, he hasn’t shown thru experience to develop in other key areas.
