And it really was a momentum changer.
I referenced it above, but the whole story on Lillard was that in the 2015 DII championship game Lillard and Cleveland Central Catholic were ahead 37-35 in the fourth quarter with 45 seconds left he drove to the basket and threw down a beautiful monster dunk to give CCC a four-point lead that Defiance would have had a very tough time overcoming. Unfortunately, he realy hung on the rim with his feet coming up nearly level to the bottom of the backboard, and the referee T'd him up for hanging on the rim. Defiance went to the other end hit the two free throws then scored to tie the game, eventually winning in overtime. Instead of a two-possession lead, the technical let Defiance back into the game.
Here's a link with the video. The lesson for Lilland is that "dunks are bad."
