What is the psychology underpinning of this phenomenon? Aluma miss 5 foul shots in a row, at a very important time in the game. What was he thinking? What had gotten into his head?

At the end Aluma and Radford kicked it up a notch and decided we weren't going to lose. What goes into this thought process? Why do they make this change in the last 8 minutes of the game and not half-way through the first half?
