The NBA is officially back starting tonight, and Nike's new commercial will get you inspired for the game, even if you aren't a Cavaliers die-hard. Simply put, any basketball fan has to appreciate LeBron James' infamous block from Game 7 -- the jaw-dropping move that essentially sealed Cleveland's come-from-behind Championship win over the 73-win Warriors. The Block is the focus of Nike's new ad, entitled "Come Out of Nowhere." Narrated by King James himself, the clip extols the virtue of the underdog, who defies expectations by seizing the moment when it counts. Watch the clip below.
