Splash hire!
But not because it's "splashy," but because Miami deserves the very best coordinator we can get and we big game hunt now. I'm not a big fan of the continuity argument. I think it's lazy. I am a big fan of data, probabilities, and such. The odds of the best candidate for DC at Miami already being here as a LB coach is very low IMO. Keep in mind that in two years, jobs at Miami are going to be even more desirable than they are now. There will be proof of concept. The next time we replace a coach his replacement will be better than he is.
My opinion. Which is worth 2 cents. Don't tell my clients that, though.
