Dallas Mavericks rookie guard Dennis Smith Jr. surprised some when he signed an endorsement deal with Under Armour earlier this offseason.
Kevin Plank, the Under Armour CEO, joined Instagram earlier this week. One of his first posts was the dominant dunker, who will join Stephen Curry as an Under Armour endorser, putting him on a poster.
Smith, who we predicted could eventually become a slam dunk champion, recorded a ridiculously impressive vertical leap when working out with the Los Angeles Lakers before the draft.
Watch him put his athleticism to good use as he flies over Plank in this post.
