Shaquille O'Neal is a first-ballot Hall of Famer who, despite his dominant career, left plenty on the table.
Not to sound presumptuous when it comes a top 10 NBA big man, but I've always thought Spurs fans looked at Shaquille O'Neal a little bit differently than fans of other teams. And, when I say "looked at" - let me just come out and say it - I mean that we feared him. The man was as big as a mountain; a living, breathing Game of Thrones character in signature sneakers. When Shaq established position in the post, it was like the moment just before the roller coaster goes over the first hill when your heart starts to go into your stomach.
