"Who?" was LeBron James' response to a reporter asking him about Under Armour in a post-game interview following last night's Cavs/Celtics game.

James went on to insist that he didn't know who Under Armour was, underlining that he's a Nike lifer.

"I don't know what you're talking about," James claimed. "Who? The other guys? I don't know who Under Armour is, I only know Nike."

The reporter asked about an Under Armour commercial only to be cut off by James, who clearly wasn't interested in talking about any sportswear companies other than the one he just signed a lifetime deal with.

James also spoke on his Nike Flyease sneakers in the interview, touching on his feelings after seeing Special Olympian Aaron Miller wear them last night.
