I think what we need to realize is that it’s pretty quantifiable a fact at this point that Beilein - either in how he prioritizes recruiting, player development, or scheme (or all of these) - doesn’t care about defense as much as offense. The best defenses he’s produced have managed middle of the pack in the Big 10, the best offenses have been tops in the nation. This isn’t the NBA - the kids who can fill it up and defend like demons stay in the NCAA for a year, and go elsewhere. As a coach, Beilein needs to choose what skills to prioritize (surprise - it’s obviously shooting and passing) and coach to those strengths, and that’s what he does.
It should be blindingly obvious by now - whether you like it or not - that given the opportunity to play a floor spacing defensive liability at the four or a towering rim protector, he will choose the former literally every single time.
He will always choose to play Robinson at the four rather than move Wagner down to make room for Teske in the name of rim protection. Always.
This is not to say he “doesn’t care” about defense - but when our team has hummed, it’s been because we score at a rate nobody can match.
