The Cavaliers were blown out by the Celtics in Game 1 of the Eastern Conference Finals, but LeBron James remains optimistic about his team's chances.

“I have zero level of concern at this stage,” James said. “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. 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. We have another opportunity to be better as a ball club coming in Tuesday night, and we’ll see what happens.”
