LOS ANGELES — As a standout forward on an Oregon team that entered the season ranked fifth in the nation, Dillon Brooks had lofty expectations for his junior season. He hoped to help the Ducks defend their Pac-12 Conference title. He hoped to lift his stock among N.B.A. scouts and possibly bring a national championship to Eugene.

What he never predicted was that to do any of that, he also would have to overcome viral video infamy.

“I couldn’t even go on my phone,” Brooks said of the days after cameras caught him in a theatrical flop in a game against Utah in late January. “I had to turn it off.”
