One thing I've been noticing lately (not just this game, though it's extra bad today) is that our spacing on offense is terrible. Every time there's a drive or we run a pick and roll, someone is standing near the basket so that their defender can help.
Notre Dame is clearing out on their drives, so they get us 1-on-1.
