LeBron James and the Cleveland Cavaliers were throttled at the TD Garden in Boston on Sunday afternoon, as the Celtics coasted to a 108-83 victory to take a 1-0 series lead in the Eastern Conference Finals. Despite the 25-point loss, LeBron isn't panicking and he remains just as confident in his team's ability to bounce back in Game 2 on Tuesday night.

Following the loss, in which LeBron turned the ball over a playoff career-high seven times, he told reporters he had "zero level of concern."

"I have zero level of concern at this stage," James said, per ESPN. "I didn't go to college, so it's not March Madness. You know, you get better throughout the series. You see ways you can get better throughout the series. But I've been down 0-1, I've been down 0-2, I've been down before in the postseason. But for me, there's never no level of concern, no matter how bad I played tonight with seven turnovers, how inefficient I was shooting the ball.

"I'm just as confident going into a series whether it's a 0-0 series or I'm down 0-1. So we have another opportunity to be better as a ballclub coming in Tuesday night, and we'll see what happens."

LeBron finished with 15 points on 5-for-16 shooting, nine assists and seven rebounds in addition to his seven turnovers. As a team, the Cavs shot just 4-for-26 from three-point range and they were outscored in the paint 60 to 38.

"They punked us," Tristan Thompson told ESPN. "Early and often."

Game 2, airing on ESPN, will take place at the TD Garden in Boston tomorrow night at 8:30pm ET.
