After a trying though ultimately successful rookie season, Zion Williamson has ascended into the upper echelon of NBA players in 2021 and there's every reason to believe he could top that list relatively soon.

Stardom was predicted for Williamson long before the Pelicans made him the number one selection in the 2019 draft, but he dealt with injury problems and conditioning issues as a rookie before the pandemic put the season on hold for a few months.

He still managed to average 22.5 points and 6.3 rebounds while shooting 58.3 per cent from the field in 24 games. Williamson finished third in the Rookie of the Year voting behind winner Ja Morant and Kendrick Nunn, but there's little doubt that he would've taken home the award had he been healthy for a full season.

Now slightly leaner and more in attack mode, Williamson has taken his game to another level in his second season, doing things rarely seen in league history. He ranks eighth in the league in points per game (26.9) and that has come on 61.7 per cent shooting, a level of scoring volume and efficiency few players have ever approached.

Only two other players have previously shot 60 per cent while averaging 25.0 points per game and both trail Williamson. Kevin McHale scored 26.1 points on 60.4 per cent shooting in 1986-87 and Charles Barkley had 25.2 with 60.4 per cent shooting in 1989-90. Shaquille O'Neal in 1993-94 (29.3 points, 59.9 per cent) and Amar'e Stoudemire in 2007-08 (25.2, 59.0) are next on the list.

Of those, Williamson's body most resembles Barkley. Both measure 6ft 6in, though Zion is far more muscular, while McHale (6ft 10in), O'Neal (7ft 1in) and Stoudemire (6ft 11in) all had the advantage of playing much closer to the rim. Williamson's field-goal percentage this season is on pace to be the highest ever by a player of his height or shorter.

After Barkley's 1989-90 season, a second campaign from the former Philadelphia 76ers superstar ranks third for the highest field-goal percentage at this height, shooting 59.4 per cent in 1986-87. That mark was matched by 6ft 5in Mike McGee three years earlier.

Williamson won't turn 21 until July and is just the 10th player in NBA history to achieve All-Star status at 20 years old. The others on that list are Luka Doncic, Anthony Davis, Kyrie Irving, LeBron James, Kobe Bryant, Kevin Garnett, O'Neal, Isiah Thomas and Magic Johnson. Only Bryant, James and Johnson were younger when making their first All-Star Game appearance.

Perhaps Williamson's consistency has been the most surprising aspect of his stellar season. Players of his age, regardless of talent, often have bad stretches where shots don't fall or the energy is lacking, but he seems almost immune to it.

Williamson scored at least 20 points and made at least 50 per cent of his field goals in 25 consecutive games from February 6 to April 6 before that run ended with 16 points on 4-of-12 shooting in a loss at Brooklyn on April 7. His streak equalled O'Neal's record mark of 25 straight games (2001).

In a five-game stretch over February 10-17, Williamson averaged 31.6 points with a 70.1 field-goal percentage. He was the first player to average 30 points on 70 per cent shooting over a five-game span since James during his last MVP season in 2012-13. The only other players to achieve this since 1991-92 are O'Neal (January 1994, December-January 1995-96) and Dwight Howard (February 2011).

Approaching a full 82-game season for his career, Williamson already ranks among some of basketball's legends for total points at this juncture.

With 1,968 points, he ranks sixth through 77 career games among all players to have debuted since 1963-64. Just four players - Elvin Hayes (2,216), Kareem Abdul-Jabbar (2,197), Michael Jordan (2,161) and Billy Knight (2,049) - passed the 2,000 mark, while Williamson had only a point fewer than David Thompson (1,969).

Already an elite finisher, Williamson has even taken on the role of playmaker for the Pelicans with point guard Lonzo Ball sidelined with a hip injury. Coach Stan Van Gundy played Williamson at the point for a full game earlier this month, following his one-game slump against the Nets, and the result was perhaps the best game of his career.

Williamson had 37 points on 15-of-28 shooting with a personal-best 15 rebounds and career high-tying eight assists in that 101-94 victory over Philadelphia on April 9. He became the youngest player (20 years, 277 days) in NBA history to record at least 35 points, 15 rebounds and eight assists.

This is unlikely to be the season the Pelicans make noise in the playoffs, but the core of Williamson, Brandon Ingram and Ball is in place, so the franchise's future is extremely bright.

Ingram is enjoying another outstanding season and easily could've been an All-Star for the second consecutive season. He's averaging 24.2 points, 4.9 rebounds and 4.8 assists.

Williamson and Ingram are on pace to be just the fourth pair of team-mates aged 23 or younger to average 23 or more points per game in the same season. The others are Walt Bellamy and Terry Dischinger (1962-63 Chicago Zephyrs), Kevin Durant and Russell Westbrook (2011-12 Oklahoma City Thunder) and Karl-Anthony Towns and Andrew Wiggins (2016-17 Minnesota Timberwolves).

One area where Williamson does need to improve is on the defensive end. His size prevents him from guarding most opposing power forwards or centers and his 285-pound frame gives him trouble staying with most wings. The Pelicans are a potent offensive group but rank as one of the league's poorest defensive teams and that will be a point of concern in the offseason for Van Gundy.

New Orleans has long been a football town, crazy about the Saints and star quarterback Drew Brees for two decades. But with Brees now retired and the Saints in transition, the time has arrived for Williamson to become the Big Easy's most beloved athlete.
