Now that I'm not on my phone, I can actually put the full quote since clay decided to skip parts of it.
"If I come into your building for a Game 1, I can be very challenging."
Before that he was talking about seeding, so here is the full context.
"Listen, it doesn't matter to me if I'm a 6-seed or a 3-seed or a 2-seed, 8-seed," James said. "If I come into your building for a Game 1, I can be very challenging."
When you have the full quote and the full context, it gives a much different impression of what James was saying and his meaning.
