Offensive efficiency and defensive efficiency both have a correlation to winning a national championship. Offense is showing to be the much more important of the 2. You can have an elite offense and kinda ok defense and be a threat to make the final 4. The only team that is really the opposite of that is Houston. They are probably the team most known for defense in the entire country, and they gave up a double digit lead to lose the natty, which in theory, is something THE elite defensive team should never do.
We seem like we are hunting the offensive efficiency route, and hoping offense is our best defense (if you score on offense and set your defense it is much easier to get stops), and we are gonna try to make it work however we can defensively. This group is does not seem particularly switchable, our bigs in a hedge or a blitz is a terrifying thought to me, and BU plays less zone than your local AAU coach who presses 94 feet "cause that's how you play basketball."
I don't see a route other than drop coverage on screens and helping off the other teams worst shooter at all times. We are going to continue to see other teams have a guy with a career game against us, but the hope is the averages will kick in and we win more than we don't.
I am not in practice or meeting rooms obviously, but if this was my team and we weren't gonna zone, this is how we'd play defense.
