Ben Johnson is like the difference of a QB prospect who'd have been #1 for consecutive drafts and one who flashes onto the scene, which is more like Daboll. There's bust/reward risk in each, but the former is a better hit rate.
I can't think of a more consensus 1st time HC candidate since Shannahan, really.
So like yea, they have to go through the full process or whatever, but he looms over any other candidate choice.
