The NBA is filled with stories of players who rose to the top only to come crashing down when things got tough. Sometimes, an injury, a controversial moment, or the pressure of expectations causes them to lose their way. Once that pivotal moment happens, it can feel like the player never quite recaptures their old magic.
This list highlights 15 NBA players whose careers nosedived once things went sideways. Whether it was a sudden decline in performance, an unexpected trade, or off-court issues, these guys couldn’t bounce back.
15. Gilbert Arenas

Agent Zero was a scoring machine until a locker room incident involving firearms derailed his career. Once the league suspended him, he was never the same player again.
14. Derrick Rose

Once an MVP and the future of the Bulls, his career took a turn after multiple knee injuries. Though he remained a solid player, he never regained that electrifying form.
13. Andrew Bynum

A key piece of the Lakers’ title run, Bynum’s career fell apart after being traded to Philadelphia. Knee injuries and a questionable commitment to the game soon left him out of the league.
12. Ty Lawson

An explosive guard with the Nuggets, Lawson’s issues with alcohol led to multiple arrests and a steep decline. His once-promising career never found footing again.
11. Isaiah Thomas

IT was the heart and soul of the Celtics, but a hip injury changed everything. Despite brief stints with other teams, he never returned to All-Star form.
10. Lance Stephenson

Born Ready was always unpredictable, but his career became a journeyman saga after leaving the Pacers. The highlight reel moments became few and far between.
9. Markelle Fultz

A No. 1 pick with sky-high expectations, Fultz’s shooting woes and injuries derailed his time in Philly. Although he’s shown flashes in Orlando, he never became the star many expected.
8. DeMarcus Cousins

Boogie was an All-Star force until an Achilles injury made his career tailspin. After bouncing around teams, he never found stability or his old dominance.
7. Michael Beasley

A scoring talent with enormous potential, Beasley’s lack of focus and off-court issues led to a turbulent career. Teams never seemed to trust him as a long-term option.
6. Brandon Roy

A natural leader and clutch scorer, Roy’s knees betrayed him just as he hit his prime. Multiple surgeries couldn’t save his career, and he faded out far too soon.
5. Josh Smith

Once an athletic dynamo with the Hawks, Smith’s game fell apart when his three-point shot became more of a liability than an asset. His later stints in the NBA were largely forgettable.
4. J.R. Smith

A talented scorer and streak shooter, J.R. hit rock bottom after his infamous mistake in the 2018 NBA Finals. While he managed a ring with the Lakers, his reputation never fully recovered.
3. Roy Hibbert

An All-Star center during the Pacers’ deep playoff runs, Hibbert’s game didn’t adapt to the evolving NBA. Once small-ball took over, he was left behind.
