For some, the sky's the limit, which also just happens to be the title of the book written by 12-year-old British skateboarder Sky Brown.
For others, it’s no stretch that big things appear ahead. Exhibit A: 7-foot-2 Denver Nuggets center Bol Bol and his roughly 7-8 wingspan.
So many potential stars in the making. So many stages for them to shine. One of the biggest will be this summer during the Tokyo Games, which were postponed a year due to the COVID-19 pandemic.
By the time 2021 ends, a new crop of names will start to become even more familiar. So let's name-drop a few. (Sorry, Trevor Lawrence, you’re already too big of a name for this list.)
Sky Brown, skateboarding
Sky Brown, a skateboarding prodigy who has her sights locked on the Tokyo Games, turns 13 a few weeks before the opening ceremony as her sport makes its Olympic debut (along with sport climbing, karate and surfing).
Brown already has a doll made in her image and sponsors such as Nike.
He remains eligible for the rookie of the year award, with the favorites being Charlotte's LaMelo Ball (No. 3 pick overall), New York's Obi Toppin (No. 8) and Minnesota's Anthony Edwards (No. 1).
Iga Swiatek, tennis, Poland
The 19-year-old who listens to Guns N’ Roses before matches captured Poland’s first Grand Slam singles title when she won the French Open in October. Swiatek had never won a tour-level title until Roland Garros.
2020 Most Improved Player
2020 Coach of the Year: Piotr @Sierzputowsky
2020 Fan Favorite
The rookie-of-the-year candidate is the son of longtime major leaguer Charlie Hayes.
In the AL, there's Tampa Bay's Randy Arozarena, who remains eligible for rookie of the year. He earned the Babe Ruth award for the Most Valuable Player in the postseason after helping the Rays to the World Series.
Catarina Macario, soccer
The Brazilian-born Macario, a midfielder on the U.S. National Soccer Team, became a U.S. citizen this fall. That news coincided with a call to the training camp for the U.S. Women’s National Team.
Although the Stanford standout still needs to iron out her paperwork with FIFA to be eligible for Tokyo, there’s optimism she could join the U.S. at the Olympics.
JoJo Earle, college football
The speedy Alabama wide receiver JoJo Earle originally committed to LSU before joining an Alabama program that's well known for producing wideouts.
This season it's Heisman hopeful DeVonta Smith, who was named The Associated Press college football player of the year.
Alexis Lafrenière, hockey
New York Rangers forward Alexis Lafrenière was the top pick in the NHL draft after a stellar stint in the Quebec Major Junior Hockey League. Lafrenière was leading the league with 112 points (35 goals, 77 assists) in 52 games last season when play ended.
The top professional prospect on the 2020 U.S. Olympic team decided to wait so he could fight for a medal in '21. The athletic, speedy lightweight from Virginia is hoping to follow the career path of friend Shakur Stevenson, who won a pro title just three years after earning a silver medal in the Rio Games.
Yealimi Noh, golfer, U.S.
She was set to attend UCLA before turning pro in January 2019. She finished tied for second at the Volunteers of America Classic in early December.
