Explain that Nike B-Ball ad to me

You know the one. There’s some guy training in the pool, then there’s a guy sitting poolside coaching him, a little guy like Urkel jumps in the pool, then some guy with a big fro jumps off the diving board.

The Nike site calls them The Lebrons so I assume one of them is Lebron James?
Which one is him?
Are the other guys also NBA players?

Current Bron, young Bron, old Bron, Business Bron.

Ain’t computers a bitch? Those are all the same guy, Lebron James, acting all the parts. Kinda like Eddie Murphy in those Nutty Professor movies.
