I mean Hakeem had his pretty good era of dominance back when he played but I feel it was just outplayed and just a little bit under-recognised due to the amount of focus there was on other centers and players too in that era. Hakeem is still considered one of the best defensive players to ever play, but whenever someone brings up a topic of who they'd play as a big offense+defense option, people probably go with Shaq. I feel the reason for this could be cause when Shaq played, his skills weren't overlooked because there was no other big to dominate the game in that era along with Shaq.
