Mavericks No. 1 pick Cooper Flagg may have experienced his “welcome to the NBA” moment courtesy of Luka Doncic’s backup, Gabe Vincent.

In Wednesday’s marquee preseason game between the Dallas Mavericks and the Los Angeles Lakers, Vincent torched Flagg—who was his primary defender—for an impressive 18 points in just five minutes. Vincent was unstoppable early on, sinking five consecutive three-pointers to start the contest. Although he missed his sixth attempt, Flagg fouled him on that play, sending the Lakers veteran point guard to the free throw line for three shots.

At that moment, Flagg appeared to have no answers for Vincent’s offensive onslaught.

NBA fans were left in disbelief at Vincent’s performance, especially considering it came against the highly touted rookie. Flagg had previously held his ground well against other veterans in three preseason games, with his defense being a particular highlight.

That made Vincent’s relentless scoring blitz all the more surprising.

Here’s how fans reacted to that electrifying stretch:
