Another key note is he evolved on the defensive end as well, going from more of a Syracuse zone type to installing one of the toughest, man to man switching schemes in college.
Think about the antithesis of that (Boheim), who has effectively spent his whole career just doing the opposite. Same scheme, same players.....just stick with it. That is how college coaches typically are.
Beilein is incredibly flexible with what he does.....he considers how the competitive landscape is changing and tries to evolve with the times. You have to be a good coach to even consider that type of year-to-year change, a great one to excel and succeed while doing it.
He's also been phenomenal at playing to his personnels strengths. I mentioned this in a previous post but this is a coach that made a national title game with Trey Burke and Xavier Simpson at PG. Think about how wildly different the engines of those two offenses are.
