"I was just ready to quit," Boogie told ESPN's Rachel Nichols in an interview that aired Wednesday. "Like, throw the towel in. Human nature, first thing is like, "Why? Why me? Why now? What did I do wrong? Why do I deserve this?' "
Cousins was playing in just the second playoffgame of his 10-year NBA career, and had just overcome tearing his left Achilles about 15 months prior.
Ultimately, he refused to accept that he wouldn't suit up again this season, and went above and beyond to return to the court.

"The physical part wasn't the hard part. It's everything mental that comes with it."
About six and a half weeks after tearing the quad, Cousins returned to action for Game 1 of the NBA Finals against the Raptors. He played just eight minutes off the bench.
Shortly before the opening tip of Game 2, we learned that Warriors coach Steve Kerr had inserted Cousins back into the starting lineup.
The two-time All-NBA selection delivered in a big way, racking up 11 points, 10 rebounds, six assists and two blocks in 28 minutes as the Warriors evened the best-of-seven series at one game apiece.

"I had to dig deep. I had to do some soul searching ... I couldn't go out that way," Boogie explained. "I've been doubted my whole life.
"I made it a mission to prove those people wrong, and I'm gonna continue to do that."
