LeBron James's future at Cleveland has been thrown further into doubt after reports that the Cavs' sluggish offseason has frustrated the NBA's leading man. Last season ended poorly for James and the Cavs, as they lost the NBA championship to the Golden State Warriors, losing 4-1 in the Finals. Frustrations were compounded just a week later, when Cavs chairman Dan Gilbert announced general manager David Griffin would be leaving the team, while James had been in favor of extending his contract.
