This:
My brother in law happens to be very good friends with a former Patriots and Colts player who explained that McDaniels was all but assured to be the next HC a few weeks ago. After the first interviews, he was the #1 guy and had essentially tentatively accepted the job. This former player was pretty excited because he felt McDaniels had really learned from his stop at Denver and then coming back to become an OC to see where he had went wrong and to correct those mistakes.
I hope the Colts go after some one that isn't just a retread of a hire like Fisher. It might take 4-5 years of building to get back to where the Colts can compete in their own division with Tennessee and Jacksonville looking like they will be incredibly good for the foreseeable future.
Build for 3 years from now (likely Luck sits out another season and needs another full year to get back) with a focus on the defensive line, LB's, and WR's...the Colts should be more than ready to compete.
