If we want to be completely honest, then let's do it. Our defensive strategy is going to result in some open three pointers. A team that specifically hunts for them like Maryland is going to result in more than "some" open three pointers.
Maryland is 289th in the country at shooting the three. Them shooting a three pointer is a desired outcome. Anthony Cowan is great at driving and getting to the line, and Jalen Smith is a beast inside. If we prevent those and instead Hakim Hart or Eric Ayala launches a three... that's a decent defensive possession.
Yesterday was a 68 possession game. Maryland turned it over 9 times. Let's say they shot three pointers on the other 59 possessions and made their season average of 30.9%. That would result in 18 or 19 made three-pointers for a total of 54 or 57 points. In a 68 possession game, this is a fantastic number.
Is this sort of defensive strategy going to win you a championship? Almost certainly not, at some point a team will get hot and beat you. Is this sort of defense something that would work in the NBA? No way, the shooting is too good.
But for this team, this year, it makes sense. It's designed to win us enough games, which it's looking like it has.
We have the 16th-best 2P% defense. Only a handful of high-major teams rate better that and you're talking about teams like Seton Hall and Kansas (top-12 teams with defensive stars inside) and Virginia and Washington (coached by defensive wizards running the pack-line or the zone).
To ask our 3P% defense to be just as good is asking for a lot of luck (Memphis has benefited from this) or to be one of the best teams in the sport (like Michigan State and Houston... and we have not recruited nearly at that level).
