Watch the best dunks from NBA Rookie photo shoot day

The NBA's 2014 class of rookies put on a dunking exhibition yesterday during the NBA Rookie Photo Shoot media event. What started as a dare between Glen Robinson III and Zach LaVine quickly turned into an all out impromptu dunking contest. Here are some of the best ones...

The Sixers' KJ McDaniels' behind the backboard lob to Jerami Grant:

Magic's Aaron Gordon's off the wall, cartwheel self-lob

Marcus Smart's pass off sideboard for a spinning Markel Brown

Brown, who earlier in the day declared on Reddit  his athleticism rating in NBA 2K15 should be "100", then showed off this between the leg off a bounce.

Thunder's rookie duo Mitch McGary's soccer pass to Josh Huestis

A looong alley oop chain, from Elfrid Payton to Cleanthony Early to James Young to Jabari Parker to Aaron Gordon to Walter Tavares.

But the winner of best dunk goes to Mitch McGary, with this, um, thing.
