I am not in favor of college coaches who recruited the best high school players in the country then compiled ridiculous winning records with that talent. The Cowboys need a coach who has demonstrated he can get more out of the talent he has because there is no recruiting in the NFL. There is the opposite- a salary cap. I am not saying Meyer or Riley would not be better coaches than Garrett in the NFL, but I do think there is risk to those guys.
I think Harbaugh could do wonders with this Dallas team, but guys like him have a short shelf life. If players hate playing for him, he probably has two years before this starts to cause problems. Something tells me Jerry wants a coach who will hang around a little longer. So do I.
Suggesting Rod Marinelli as an option discredits the entire list and the guy who made it, especially with Dallas in the middle of what looks like a defensive disaster. Seriously, what does Marinelli add to this team as a HC?
Finally, beware of the Johnny come latelys. Greg Roman looks like a genius in Baltimore, but I think Lamar Jackson has a lot to do with that. Dak cannot run like Jackson. Did Roman make Jackson or the other way around. I think Jackson is making Roman look good. Robert Saleh is another guy. He seems like he ticks all the boxes, but the season is not over yet. The 49ers have great defensive personnel. I bet even Marinelli could win with that defense. Maybe Saleh is the guy but I'd want to know a lot more about him.
Its a tough call and I hope Jerry does his homework. He has an underperforming team and the guy he picks needs to fix that.
