Actually, I'd be very much in favor of Josh McDaniels.
Before any crazies jump on me, yelling about Josh's terrible stint as Broncos head coach, I'd argue that McDaniels has probably matured a lot in the years since then, especially working under BB. Working under BB is a huge plus for me. Hate him all you want, and I know people will, but Belichick is surpassed in coaching talent by nobody. Sean Payton, Gary Kubiak, and Mike McCarthy are close behind him, but yeah.
And, by the way, even Belichick was a sucky Browns head coach before becoming the Emperor of the NFL. I wouldn't be surprised to see McDaniels take a similar career arc.
