I'm surprised people didn't already know this. Last year it was the same. In 2K16 you looked at your stats after a Pro-Am game and your real overall would appear. I remember Stretch Cs had a particularly low overall in comparison to other builds, because the overall undervalued shooting.
Does it really matter though? I mean, anyone who plays modes outside MyCareer knows overall isn't a particularly good measurement of how useful a player is in a game. Overall's just a formula for casuals to lean on and a means of fueling conversation on the internet.
Yea, makes perfect sense given On-Ball Def IQ, PnR Def IQ, Help Def IQ and Low Post Def IQ are all maxed on defense. Not sure if it's changed, but in previous games IQs were a means of artificially raising/lowering overall ratings.
Do those defensive IQ ratings have a significant impact on how your player plays when you control the player?
In 2K16 MyTeam I paid particularly close attention to Help Def IQ, because my experience was the CPU would make help mistakes when the rating was below 75.
