Kevin Willis and Malik Rose made Shaq (and Kobe, Fisher, etc.) cry and that didn't get them a spot on that list, tbh.
Hustling for the camera doesn't really make someone a good defender, tbh. In fact, diving into the fifth row is usually bad strategy, if we're being honest. The offensive equivalent would be like saying someone is a good offensive player because they do a lot of no look passes. I can't remember a standout "hustle play" from Duncan or Robinson but they were obviously great defenders.
Having Jordan and Pippen on your team and winning by 50 or whatever would make anyone look like a great defender
Shaq still played well in that game and in that series. If Shaq and Rodman switch teams that series, the Bulls sweep the Magic by an average of about 80 points.
Bill Laimbeer was a more important player to those Pistons teams and no one even thought about putting him on the top 75. Taking away the wedding dress, the hair color, the antics, the historically great teams he found himself on (that would have been great with or without him) and Rodman is Reggie Evans with worse offense.
