"So it's always easy to bounce back after a loss, and now it's our turn to see how we're going to handle our loss and how we're going to respond."
Big Three against Big Three provided plenty of buildup to the series, and Ginobili said the Spurs stand little chance of winning if their trio plays poorly.
But James, having seen the Heat not have enough when they were largely just he, Wade and Chris Bosh two years ago, insists his current team is deep enough to do big damage even when it doesn't come from the big names.
"I think the supporting cast is really why both teams are here," James said. "They've been making an impact all year long, and they feel like their supporting cast is better. We feel like our supporting cast is better. It's who goes out and do it each and every night to help seal wins."
The Spurs are shooting just 41 percent and averaging 88 points in the series, perhaps lucky to not be down 2-0. Duncan, the three-time NBA Finals MVP who always seemed to be more reliable the later in the season it was, has made only 11-of-32 shots.
"Obviously, they're contested shots, but they're the shots I feel I can make. So whether it be them or me or whatever it may be, I'm going to get back in the gym tomorrow and hopefully come out with a better stroke," he said. "But I'm getting the shots I want. I just have to knock them down."
