Gilbert became a viral sensation when he wore a bow tie and dark-rimmed glasses in the 2011 lottery draft. The Cavaliers ended up getting the first pick and selected Kyrie Irving first. It was a season after LeBron James left the team to sign with the Miami Heat.

Then, at age 14, Gilbert quipped, «What’s not to like?» after his father praised his efforts and called him his hero.

He represented the Cavaliers in several other lotteries. Cleveland would get the No. 1 pick in 2013 and 2014. The team would draft Andrew Wiggins in 2014 and send him to the Minnesota Timberwolves in a trade that landed Kevin Love. James, Irving and Love would help bring Cleveland a championship in 2016.
