1. Adding the 1-3-1 as a defensive option. It's the fastest growing defense in D-1 in actual CBB, used MUCH more often than a 3-2 zone, and nearly as often, if not more than a 2-3 these days.
Other things:
-Fixing A:T ratio, it's just so far off actual A:T ratio.
-Being able to intentionally foul when up by 3+ with less than 10 seconds . This is a big thing to me because it's used so commonly now and is the quintessential coaching dillema late in games.
-Recruiting overhaul; specifically, make it less about just how much money you spend and more about how a guy likes your school and what things you can market about your school(playing time, location, etc.).
-making IQ more importand, but making the points easier to pick up. IE, most teams can play effectively a press, a man, and at least ONE type of zone in CBB today. There may be a base defense, but from game to game, and even within the game, teams will fluidly change from man to zone or press to not press, and there's not a massive drop off.
Here, there's no point to learning all 3 defenses, and I think that's unfortunate and leads to predictable gameplanning.
