Kyrie Irving and LeBron James were out and running early and often in Game 1 of their second-round series against the Toronto Raptors on Monday, and they capped a 10-0 run in the first quarter with this ridiculous alley-oop, as Irving went high off glass on the feed and James hammered it home with one hand.
