This was mentioned in another thread and I've advocated for it off and on for years, but I wish/think that IQ should also have potential and have a cap (besides the A+ cap smart guy). It's stupid that with enough practice every kid on every team (minus maybe the extremely low WE guys) can reach A+'s by their senior seasons. As was said before, some kids just don't "get it". Some do. Some fast, some much faster than others. Some at a Stephen Hawking level. Some slow. Some are dumber than a bucket of hair. Some dumber than the day is long. You get the point
It would certainly add another dimension to the game. Do I recruit the badass ratings kid who won't ever get higher than say, a B- in the O and D? Or do I take the coach's son, who has solid ratings but is a whiz on the court and will hit A+'s extremely fast? Do I "really" want that PG running my offense if he can't get his IQ over a B?
It just seems stupid to me that every other rating and category in this game is based off of potential, with a cap, and arguably the most important attribute of all works on a linear level where EVERYBODY (again, the low WE guys, I know) can reach the same highest level.
Furthermore, to me, reaching an A+ level should be extremely difficult. I'm talking the high GPA, high WE kids, maybe even having to have the fifth year (redshirt) to get there. Make it actually MEAN something. Make the higher your IQ gets, the more efficient your player gets. Noticeably. Make the coach makes some damn decisions instead of getting everything spoonfed to us like we are now. It's far too easy as it is now to get a player's IQ to a max level while also maxing out his individual ratings. Choices, life is FULL of them. Make one. Do I want a smart, well trained team or do I want an extremely heavy "ratings" team who plays more undisciplined on the court? Choices, make one. Stop with the spoonfeeding. Add some decisions to the game. Make coaches actually have to stop and contemplate the results of their actions and whether it benefits the team long term but hinders them short term, or vice versa.
This game has a lot of small things that could be improved upon, but in this humble opinion, having IQ based on a linear scale is the biggest "error" in the game today. Also, BY FAR, the most unrealistic. My two and a half cents.
