Of the six losses we have, looks like a couple were mostly due to poor defensive rebounding, a couple to poor FT shooting, and a couple due to our inability to make treys. So those are definitely keys to our success.
I would also add hustle plays, just beating the opposing team to loose balls. Extra possessions are critical in close games. Seems like the opposing team scores 2/3's of the time when they get second chance opportunities, probably because your defense is often not set. So limiting second chances by limiting offensive boards and beating them to loose balls, is very key.
