Miami Heat guard Tyler Herro is certainly enjoying the notoriety he got after his breakout performance in the 2020 NBA playoffs. So much so that the 20-year-old sharpshooter has begun sporting his own merch, as he was seen donning a black shirt in practice with an image of his now-iconic mean mug.

Images of Herro wearing his statement shirt during practice has gone viral on Sunday, with some fans already asking where they could avail the tee.

Tyler Herro's mean mug, of course, came on the heels of Game 3 of the NBA Finals against the Los Angeles Lakers after the rookie drilled a dagger to seal the victory. A lot of pundits were claiming that the Heat would get swept by LA after falling 2-0, so Herro's epic reaction was indeed directed to all those doubters.

The Kentucky product had a solid outing in his first NBA season, helping the Heat clinch the fifth seed in the Eastern Conference. His true potential, however, was unleashed in the postseason after head coach Erik Spoelstra gave his utmost trust to the promising neophyte.

Herro passed that test with flying colors, coming up big in crucial stretches for Miami en route to their bridesmaid's finish in the 2019-20 campaign. Heat superstar Jimmy Butler even paid homage to Herro's heroics when he wore Tyler's n0.14 Whitnall high school jersey after that Game 3 explosion.

Herro notched 13.5 points on 38.5 percent shooting from downtown in 55 regular-season games. He bumped those numbers to 16.0 points in 21 playoff games. The Heat, meanwhile, have already acknowledged Herro as a crucial building block for their future.

For sure, he'll have a lot of chances to display more mean mug in the coming seasons.
