Shaquille O'Neal has had an illustrious NBA career spanning many seasons. Shaquille O'Neal is a 4-time NBA Champion and a 3-time Finals MVP: he knows what it takes to win at the highest level. He also knows what greatness looks like. Shaq wouldn't have been able to be a winning player without winning teammates, and there have been many elite players that he has played with during his career.
Recently, Shaquille O'Neal created an Instagram post that compiled various photographs of the elite guards that he played with. The post includes plenty of Hall of Famers and it shows just how elite some of those players were.
Shaquille O'Neal has obviously played with some of the greatest guards to ever play the game. Kobe Bryant is his most famous running mate due to their three-peat, but Shaq has also won a title with Dwyane Wade while getting to the Finals with Penny Hardaway. Shaquille O'Neal is a winner, and he knows how to recognize winners. O'Neal mentions having G-14 classification to say the things he says: that could be referring to the recent pushback he has received based on his comments about guards like James Harden and Donovan Mitchell.
Shaquille O'Neal is certainly qualified to comment on the NBA. He has played with many All-Star caliber guards throughout his career, all of them great in their own way. This post seems to be O'Neal's way of saying that he knows what he is talking about when it comes to being a winning basketball player.
