Giannis Antetokounpo is widely recognized as one of the NBA’s best players. As the reigning back-to-back MVP, he’s also got the accolades to show for it.

But even Giannis isn’t without flaws and, on TNT’s “Inside The NBA,” former superstar big man Charles Barkley explained why the 4x All-Star still has a lot of work to do…

“Giannis has got to get better as a player, Ernie…. he’s got a long way to go as a player. You are playing against 2 good teams and 5 bad teams so your numbers average out. They got beaten 2 years in a row, exactly the same way. We were talking about the “Toronto wall” two years ago, then they get beat by the “Toronto wall” last year.
