SAITAMA (Japan) -- Luka Doncic, an Olympic rookie at 22 years old, is a player who may still be some years away from his best basketball.Sergio Hernandez does not need to wait for the call to be made.Argentina's coach stated, "For me, this is what I said two years ago: He was the best player in all of the world, even the NBA." "And if you had any doubts in your mind, they are gone now. He is the greatest player in the world."After Doncic's performance at the Saitama Super Arena on Monday, it's difficult to disagree.Doncic's spectacular Olympic debut was tied for the second highest total in men’s basketball history at the Games with 48 points. This helped Slovenia win 118-100.Doncic scored 31 points during the first Olympic match in Slovenia. This puts him on pace for breaking the Games' scoring record of 55 by Oscar Schmidt, the Brazilian Hall of Famer.Although he wasn't as involved in the second quarter due to Slovenia's large lead, the Dallas Mavericks' guard kept his feet on the ground well into the fourth quarter. He was tied with Eddie Palubinskas who had 48 points for Australia at the 1976 Games in Montreal.Doncic was still able to break the record, even though he didn't want to pursue more points.Luka Doncic scored 31 in the first half of Slovenia's Olympic debut game. He ended with 48 points, which tied him for second in basketball history. Eric Gay/APHe said, "I don’t care about records." "We won and that's why we came here."Both were desired by his teammates."Everybody was telling him, on the bench," veteran Zoran Dragic stated.But that is not the case. It is important to win the game. He is aware of that fact, which is why he is only 22 years old.Slovenia was not even eligible for the Olympics at the time of this writing, but Doncic's historic first postseason in NBA made him a medal threat.Luis Scola scored 23 points in Argentina's win. Facundo Campazzo, of the Denver Nuggets, added 21.Luka versus Luis was the opening day of play for Group C. The phenom faced the veteran, who was about to begin his fifth Olympics in men’s basketball.Doncic was the show's star with 15 points just five minutes into the game.Scola stated, "He was too great obviously." He was amazing, I mean.Doncic launched his step-back 3-pointers casually from behind the international 3-point line -- one was from just inside the Games logo at the center court -- Doncic shot from areas that Argentina couldn't defend.He refused to try, and he took his game inside. He scored consecutive baskets on follow shots during the second quarter, on his way 11 rebounds.This came as Slovenia finished the half with a 23-8 win. Slovenia had a lead of 39-34 to 62-42 at break.Manu Ginobili was impressed. The Argentine idol tweeted at halftime that Doncic "was a beast" and praised his "tremendous mastery over the game."Doncic already showed that he could play in Europe, even before he was awarded Rookie of Year in the NBA. He became the first NBA player to achieve a 30 point, 8 rebounds, and eight assist average in his second season.Perhaps his first Olympics was even more amazing.Slovenia is a country that has seen great success, having won the EuroBasket title in 2017 as well as qualifying for Tokyo with a win at one of the Olympic qualifying tournaments earlier in the month. After Doncic was eliminated in round one by the Mavericks, Doncic jumped right into playing for Slovenia.Argentina, the 2004 Olympic champions were thought to have retired from their years of competing for titles. Ginobili, along with other stars from that era, called it a career.Scola is still with us and the Argentines proved that they aren't done yet when they won the gold-medal match in the Basketball World Cup two years ago. They lost to Spain, but they did win the game after securing their place in the Olympics.Spain, along with host Japan is in Group C. However, even those games shouldn’t be as difficult as playing against Doncic.Hernandez stated that Hernandez tried "everything we would have done against a normal opponent," but "he's not an ordinary player."
