Charles Barkley and Shaquille O'Neal, years after their retirement, remain two of the most popular figures in the NBA community. They are regularly seen analyzing games, when they’re not hilariously bickering for the award-winning show "NBA on TNT."The former MVPs capped off their legendary careers with their induction into the Basketball Hall of Fame. Despite their accomplishments, though, some still feel they could have achieved so much more.On his podcast, Dan Patrick stated that he saw unfulfilled potential coming from Shaquille O'Neal and Charles Barkley:“There’s part of me that looks at Charles the way I do Shaq, that he could have been so much greater. It’s not fair to say that about Charles at 6’4-6’5 power forward. But I do look at him with that talent, and I think he could have been so much better, and I look at Shaq the same way.”“He [O’Neal] could have been the greatest ever.”Charles Barkley played so much bigger than his height. Despite standing only 6’4, he was skilled enough to become one of the best power forwards the NBA had ever seen. The players who are considered to be the best at his position are significantly taller than him.“Chuck” rightfully deserves to be in the same conversation as Tim Duncan, Karl Malone, Kevin Garnett, Kevin McHale, and Dirk Nowitzki. During Michael Jordan’s prime years, Barkley was viewed by many, including Dream Team coach Chuck Daly, as the second-best player in the NBA behind Jordan.NBA TV@NBATV"They changed the rule because he was so good."Charles Barkley is one of the most unique players the game has ever seen. #NBA753005376"They changed the rule because he was so good."Charles Barkley is one of the most unique players the game has ever seen. #NBA75 https://t.co/6AY7ztzXU6Shaquille O'Neal, on the other hand, had none of the undersized problems that Charles Barkley faced throughout his career. Shaq is a man mountain with the mobility of a smaller player. The three-time Finals MVP had arguably the most dominant peak in NBA history.The “most dominant,” however, was the title Shaquille O'Neal seemed obsessed with. He and Wilt Chamberlain stand on the plateau of the most overwhelming physical forces the league has ever seen. Shaq, though, could have been a staple in the greatest ever conversation had he had more years of greatness.Hoop Central@TheHoopCentralShaq Lakers mixtape…Most dominant player of all-time.
