Coach C has the characteristics of the great coaches. First and foremost, he adapts his offense/defense schemes to the players he has. Doesn't try to fit square pegs into round holes. For a school like IU that is key, because your talent is going to vary based on who you can land. You're not going to have your pick of the top players, yet.
Second, he seems tough without being obnoxious. I don't want my football team to LEO. I want them to kick a$$ and take names. You can be tough but fair -- leading to accountability, leading to discipline on the field. No stupid penalties, etc.
Finally he believe is multiplication -- a unit of 11 guys, executing to perfection, ends up being more than the sum of it's parts.
