It appears the purpose of the memo is that Coach K's system is outdated. I don't get that at all. I have no problem with defenders funneling their men into Mark Williams. That's classic help defense. The problem I have is when the weak side help isn't paying attention and moving over to protect the basket. I get that they are always protecting against the 3 pointer but that has nothing to do with protecting the basket in situations like this.
I respectfully disagree that the intent is to "funnel" their men into Mark, like it's a deliberate choice. My apologies if that's not what you meant.
The ball pressure/overplay extends our defense to the point where it makes it too vulnerable to lane penetration too often. That makes Mark too vulnerable as a help defender. Yes he blocks some shots but too often him making that commitment leaves us vulnerable on the defensive glass. But that isn't his fault. It's the ineffective, anachronistic overplay in the first place that's the primary problem, although I'll certainly concede we could make a better effort collectively in terms of defensive rebounding.
The defense sometimes works against inferior competition but it doesn't work well against good competition generally speaking. We don't generate enough turnovers against good teams consistently enough to justify the vulnerabilities to which it exposes us. How many times over the last 10 years have we watched games and complained about how many layups and back door cuts we give up?
Moreover, it is the single biggest factor in most of our NCAA Tournament losses since 2009, where we've given up 43 or more points in the 2nd half in 6 or 7 of those losses, 3 or 4 times giving up over 50, and one time giving up 65. 65! It's hard to score 65 points in one half against air. And the reason isn't bad luck. It's bad strategy, exacerbated by a thin bench.
I honestly didn't arrive at this place on my own. I've had this conversation with probably three dozen people over the years, a number of whom have basketball coaching experience. Two in particular at the collegiate level.
All that said, I do think it could work better than most years because we have some good athletes and defenders, with rim protection. And it's still evolving.
I hope like hell I'm wrong and by the end of the year we're a defensive juggernaut.
