Atlanta Hawks forward John Collins had an awesome night of dunking during NBA All-Star Weekend in Charlotte, N.C.

Unfortunately for him ... that night came Friday.

On Saturday, Collins failed to advance to the final round of the NBA Slam Dunk Contest, finishing last out of the four-player field (along with Hamidou Diallo, Dennis Smith Jr., Miles Bridges).

Collins connected on both dunks, guaranteeing middling scores of 40-plus points. 

However, from an artistry perspective, the second-year pro lacked the creativity, vertical grace and power of Diallo, Smith and even Bridges – who rebounded from an ugly opening miss (bottom-rung score of 33) to post the evening's first perfect dunk (50 score).

NOTE: Diallo captured the Dunk Contest honors, with his signature dunk (over Shaquille O'Neal) paying homage to Dwight Howard and Vince Carter.

On Collins' first slam, he sprinted baseline left, jumped high in the air, grabbed the basket support with his left hand ... and then followed through with a power jam with the right hand

It might have been a show-stopping dunk during the regular season, or even during Friday night's Rising Stars Challenge – when Collins threw down a bevy of creative monster slams, attracting tons of attention on Twitter – but it missed the thrill-seeking mark for the actual contest.

For Collins' second slam, the Wake Forest product recruited a number of NBA players in leather jackets and pilot hats to re-create the Wright Brothers' first attempt at flight in 1903 (Kitty Hawk, N.C.)

Collins then solicited the help of Hawks teammate Trae Young to model his own pilot's garb, complete with aviator goggles and a very-long white scarf.

For the coup de grace, a large-scale replica of a model airplane sat underneath the basket. 

For the slam, Collins then cleared the plane (sort of) and threw down a cool horizontal dunk.

But alas, it wasn't enough to propel Collins to the final round.
