The unwavering belief of Giannis Antetokounmpo, now NBA champion and Finals MVP

From the beginning, Antetokounmpo has held himself to a preposterously high standard

Giannis Antetokounmpo was all the way at the end of the bench, dead silent, his Milwaukee Bucks on the wrong end of a brutal blowout. The loss burned him, but all he could do is pledge to be better, to do whatever it takes to bring the franchise a championship. It was a bit dramatic for a summer league game. For Antetokounmpo, though, the 100-71 loss to the San Antonio Spurs wasn't just any summer league game. It was his last chance to get a win in a Bucks uniform before jetting off to play for Greece's national team. He was 20 years old, coming off a rookie season in which Milwaukee had gone 15-67, the worst record in the NBA. He had not planned to leave Las Vegas without a single victory.  Antetokounmpo lamented to reporters that he hadn't won a game in months, then took to Twitter: "I'll never leave the team and the city of Milwaukee till we build the team to a championship level team," he wrote.
