In case you didn't know the name Greg Brown III, you should now take note. The Portland Trail Blazers rookie just came up with what is easily the best dunk of the Summer League in Las Vegas. It was soo good that even Los Angeles Lakers superstar LeBron James could not contain his emotions after witnessing that epic flush.

For starters, here's Brown's audacious under-the-legs slam — during a fastbreak (h/t ClutchPoints on Twitter):

If they count the Summer League, then this is probably going to be a Dunk of the Year candidate. I mean, who does that? Apparently, Greg Brown III does. He had the entire crowd on their feet after this mind-blowing slam.

LeBron James quckly took to Twitter to share his jaw-dropping reaction to Brown's insane dunk:

LeBron has taken notice of Greg Brown III, so it might be a good idea for the rest of the league to do the same.

The Blazers acquired Brown from the Pelicans after New Orleans selected him in the second round of the 2021 NBA Draft. Portland sent cash considerations and a future second-round pick to the Pelicans in exchange for the 6-foot-9 forward.

Brown, 19, is coming off one season with Texas where he averaged 9.3 points and 6.2 rebounds per game. At this point, however, it remains to be seen if he's done enough to earn a roster spot for the Blazers this coming season. If you ask LeBron James, though, he's probably going to say that this kid deserves a shot.
