In a vacuum maybe there's some truth to this. But in reality the psyche of a team is a fragile thing. When you start losing close games & blowing leads what you "learn" is doubt.
Closing out games has been an issue for this team the last couple of seasons, especially against good teams. When any team has a lead in the last few minutes, you want to run clock. The problem with that for our team is we don't really have a steller 1 on 1 guy who can get his own look when the shot clock is running down. We rely on ball movement to get good looks, so when we hold it at the end of games and try to make offense in 7/8 seconds vs a set defense it's not pretty. So to compensate for that a lot of times we don't try to run clock. We take the first good look we see as if it were the middle of the 1st quarter. That leads to plays like Wesley's ridiculous reverse layup attempt with 20 seconds left on the shot clock up 8 with 1:50 to go. We consistently give up big leads down the stretch of games because of this, and it goes back to last season. W'e've lost enough games this way to where I don't know how much more we need to "learn".
