#1 Marco Belinelli
Belinelli has always been a useful player to have coming off the bench, however, he is currently having one of the worst seasons of his career. The 32-year-old is currently shooting a career low .359 from the field, and his three-point percentage of .315 is the second lowest of his career.
The Italian has enjoyed some good moments in a Spurs jersey such as when he dropped 15 points on the Magic, although these performances have been rare, and even during his biggest contributions from the bench, his shooting struggles have been visible.
The Spurs' offense has struggled badly throughout the early part of the season, and Popovich will know that better shooters are required from the bench. Belinelli has a two-year deal worth around $6 million a season, so unless the Spurs start to see an investment on the contract, they make the decision to trade the underperforming Italian away.
