"Jimmer thinks everybody is stupid," said an NBA assistant who worked with Fredette. "He thinks everybody needs to come and just turn over their offense and let him shoot it anytime he wants. That's not how the league works." After squandering his opportunity in New Orleans, Fredette was admittedly surprised last summer when he was working out in Denver and the Spurs called to offer him a half-year guaranteed contract. The situation seemed to be his last best chance to stick around in a selfless Spurs system that has revived a few stagnant careers. But the NBA assistant coach never expected the partnership to go anywhere. "He won't adjust his game for it," he said. "He'll tell you, 'This is what I did at BYU.' Well, BYU, that's a long time ago." https://ca.sports.yahoo.com/news/why-jimmer-fredette-has-been-such-a-big-bust-in-the-nba-023311779.html
Should've buckled down and made himself into an above average defender. With his shooting ability, he'd have eventually gotten a $10m plus a year contract as a 3-&-D guy.
