It’s easy to get down into the weeds and wonder about a percentage here, or a half a percentage there.
in the end, and you mention this above when speaking about the D, you have to finish.
IU’s biggest problem last year was that we were a team that had a thin margin of error that wasn’t good at closing games, Closing games can come down to luck, but it is a skill in that it is a learned response. In other words, you can find ways to lose, or find ways to win, and you can learn to be a team that does one or the other.
We lost a bunch of close games, and there are many ways that a team can find a way to lose. A missed defensive assignment here, a turnover there, a missed free throw there. It may be tired legs as you say, it could be mental fatigue, it could be personality (mental toughness, confidence, etc)
Many of our late problems were mistakes. A turnover, a missed switch, etc. but some are missed plays that can be made (look at how a Johnny Davis pulled Ws out of the hat for the Badgers). For example, I would be happy if we shot the same percentage from three this year, if I knew we were hitting daggers late.
In a nutshell:
clean up the late mistakes. Add a playmaker. Excel on the mental side of the game.
we do these three things and we’ll be better than fine.
