Athlete: Shaquille O'Neal
Brand: Reebok

Shaq's logo is one of the only successful logos to use a dunking silhouette that stays true to the player and isn't a blatant rip-off of the Jumpman. What I think really helps that be successful is the dramatic height to width ratio of the font. By making the letters so tall and narrow it makes it have presence no matter what the scale of the logo is. But, what I think is most important is how this logo became to be a representation of Shaq and not the brand that created it, Reebok. Shaq bounced from many footwear companies through his storied career and the one thing that stayed the same was his logo. Yes there were variations of it over time but they all tied back to the original. It also goes to show you how ahead of his time Shaq was to realize that his logo had more brand equity then his product with Reebok would.
