A former Slam Dunk contestant, RaptorsAll-Star DeMar DeRozan is one of the league’s best dunkers and is a legitimate high flyer. But don’t tell that to LeBron James.

Thinking he had an easy two points, DeRozan tried to score in the paint against the Cavs in Game 1 of the second-round series between Cleveland and Toronto. But coming out of nowhere, James blocked the Raptors guard at the rim.

Through the game’s first three quarters, that was James’ only block. It was however, perhaps the most impressive block of the game.
