8. Marvin Bagley
After spending the first three and a half seasons of his career in Sacramento, Marvin Bagley was traded to Detroit at the trade deadline in February, and it's paid big dividends for him. Over the final 18 games of the season with the Pistons, he shot a career-best 55% from the field while playing a career-high 27 minutes a game, averaging his most points per contest since his rookie year.
For some players, a change in scenery is all they need to be successful, and Bagley certainly looks like he's making progress toward living up to his No. 2 overall draft selection in 2018. He still has a ways to go, especially with his jump shooting. But his large frame and physicality make him very effective down low, and he's an excellent finisher close to the cup.
Questions have been raised about his defense as well, but his shortcomings on that end are not due to a lack of physical tools. Like his shooting, it's something that can be improved with good coaching. The Pistons are likely to attempt to re-sign Bagley to a multi-year deal in the offseason, so the Spurs will have to win the bidding war if they're to acquire his services.
